    Podcast #640: ATSC 2.0 Over the Air gets Better... But is it too late? Jun 20, 2014
    Show notes

    ATSC 2.0 Over the Air gets Better... But is it too late?

    Before there was HDTV there was NTSC (National Television System Committee) or as it was known by most people today standard definition. That was the standard developed in 1941 and was in effect until it was superseded by ATSC (Advanced Television Systems Committee standards) which brought us high definition television which in turn gave rise to this podcast!

    ATSC was a dramatic step forward in picture quality and capability. But being first meant there were limitations. For instance ATSC is mpeg 2 which does not compress as nicely as mpeg 4 which is used in Europe and other parts of the world. At the time ATSC was developed, 1990s, 1080p and 4K were not really on the radar. At least we had accurate color and clear pictures!

    Technology moves on and broadcast standards have a hard time keeping up. At least the ATSC is trying. The latest version of their broadcasting standard has a lot of improvements that we’ll discuss. The main question, however, is it already too late?

    What’s in ATSC 2.0?

    The main features of the standard are:

    • Non Real Time (NRT) Services - This can be ads targeted to viewers based on time of day, what the viewer is watching, or specific data about the viewer. The broadcaster can also provide a VOD service that is delivered over the air. Watch your network content when you want without a DVR. The broadcaster can even deliver content in advance and have it ready for viewing at a specific time.

    • Two Way Communication - Now when viewers watch a voting based show they will be able to vote without the use of a telephone. They’ll be able to get more information about advertised products. This will tie into the NRT services and have that content delivered for viewing on demand. Better and more accurate viewership numbers can be obtained which may save some shows that may otherwise get canceled.

    • Watch Multiple Channels Simultaneously - You will be able to set up your screen with multiple views that include widgets or other channels. You can have weather forecasts, Twitter, or Facebook along with news and sports. Essentially turning your plain old over the air system into an advanced set top box without the need for the Internet. If you have Internet the capabilities are further enhanced!

    • Mobile Broadcast - Current ATSC does not work when the receiver is moving. That will change in 2.0. Mobile devices are becoming the norm and we can see the day when you cars will come from the factory with antennas that can receive ATSC signals making it possible for your children to watch their favorite cartoons on the go.

    These are just a few of the features available in the ATSC 2.0 spec. If you want more information its available ATSC.org.

    When do I get all this cool stuff?

    You know it took broadcasters a few years to roll out HDTV to everyone. We don’t even think about those dark days any longer. The specification will be approved later this year and then its anyone guess when broadcasters will implement them. It will be at least a few years so don’t count on anything before 2016 or 2017 at the earliest. And even then, it won’t be ubiquitous.

    Does it even matter?

    Much of what is proposed in the new standard is already available today through cable or satellite augmented with the Internet. Mobile over the air broadcast sounds like it would be pretty cool but with faster data networks and more broadcasters going online with content its not really a game changer. Higher resolution, 4K, content is not even slated until ATSC 3. By then, Netflix will be streaming 4K on much of its offerings. Fast internet is the key and rural areas not serviced well by Internet providers will lag. Its also likely that the rural areas will be slower to adopt the next ATSC standard as well. We believe that most of the country will be serviced by reliable high speed Internet before broadcasters embrace ATSC 2.0 and 3.0. And at that point will broadcasters even have incentive to roll out new more costly services? Let us know what you think.


    Podcast #639: Sonos Playbar and Sub Review Jun 13, 2014
    Show notes

    Sonos Playbar and Sub Review

    We’ve reviewed multiple soundbars in the past, from a wide variety of companies, but we’ve never reviewed a Playbar. What is the difference between a soundbar and a Playbar? Quite a bit as it turns out. Knowing Sonos we expected big things, and we weren’t disappointed in the slightest. The Playbar sells for $699 (shop now) and the optional Sub for an additional $699 (shop now).

    Setup

    If you already have any Sonos equipment in your home, setting up the Playbar and Sub is ridiculously easy. If you don’t have any Sonos gear, don’t worry, setup goes from ridiculously easy to quite easy. There’s simply not that much to it. First step is to connect the Playbar itself or the optional Sonos Bridge ($42) to your home network via wired Ethernet. Our review unit included a Bridge, and Braden already had one as well, so we went the Bridge route.

    The one Sonos device you connect to wired Ethernet allows the rest of your Sonos devices to be placed anywhere in the home with no need for any wires other than power. Once you have that main device connected to the network, you can download the Sonos app either to your iOS device, your Android device, or to your personal computer. You use the app to connect to your main device - it becomes your controller - and add music sources to listen to.

    Once you have a main Sonos device and the app to control all your Sonos gear up and running, adding new devices, like a Playbar or a Sub, is as easy as telling the app you want to add a new device, clicking a button on that device, and watching it show up. You can assign the new device to a room (by room name), and you’re ready to start listening to music. Since the Playbar is a little different, setup is slightly more involved. The app asks you a set of questions to help calibrate the speaker for your room, walks you through setting up your remote so the volume buttons will control the Playbar volume.

    You connect the Playbar to your theater equipment using a single optical audio (toslink) cable. So if you have multiple sources, you’ll still need something in place to switch between them before sending the audio to your Playbar.

    Adding the Sub is just as easy as adding the Playbar itself. Tell the app you want to add a Sub to your Playbar, click a button on the Sub and that’s it. You can place the Subwoofer itself anywhere. It just needs power. The app asks a couple quick calibration questions and you’ve just added all the booming bass you need for those big explosions.

    Performance

    As is true with just about any soundbar, the Playbar is clearly better than any TV speaker we have. Adding just the Playbar itself will improve your HDTV experience. When you add the Sub along with it, you get a new dimension in sound you would never come close to in a built-in TV speaker. The Playbar and Sub cannot compete with a dedicated Home Theater receiver and good, separate left, center and right speakers, but it isn’t intended to. For rooms that don’t have the full surround sound system, like a loft, a study, a game room or a bedroom, the Playbar is perfect.

    For movies and HDTV the Playbar was as good as almost any other soundbar we’ve used or reviewed. The only one that stood out in our minds as better was the Yamaha Sound Projector from a CES demo a few years ago. But that was an almost $2000 device that was intended to simulate surround sound, The Playbar doesn’t try to simulate surround effects. It is clearly packaged and sold as a 3.0 system: left, center and right. Since we’ve had lackluster success with simulated surround in the past, the idea of sticking to 3.0 doesn’t bother us.

    Where the Playbar really excels is with music and versatility. As a pure music playing device, the Playbar is excellent. Compared with other soundbars that seem tuned and designed for TV viewing, the Playbar almost feels like it is built for music. Every genre we threw at it, from Rock to Classical, sounded great. It was crisp and vibrant, not overly hushed in the higher tones or muffled in strange ways in the midrange. It just sounded clean.

    And versatile. As a member of the Sonos family, the Playbar jumps right in with the rest of your gear to play and stream any of your music sources. It can stream your home media collection, including iTunes, and all of your online sources like Pandora, Spotify, Beats Music, Google Play, iHeartRadio and more. It can also sync with any other Sonos player to get the same music going in multiple rooms at once. For as many times as we’ve used or reviewed Sonos, we’re yet to have music synchronization issues with multi-zone playback.

    But wait, there’s more…

    This isn’t just an ordinary soundbar review, nor is it a typical ‘soundbar with a sub’ review, nor is it a ‘soundbar with a sub that can stream your music to in sync in multiple rooms’ review. Turns out this review is also about full 5.1 surround sound without wires … without speaker wires at least. You can actually add two additional sonos players to the rear of your room and turn the 3.1 Playbar + Sub int a full 5.1 surround system, with true surround speakers, not simulated ones. All they need is power.

    We added two Play:1 ($199) speakers to the back of our test room and gave it a shot. Adding them was as easy as anything else. Tell the app you want to add a stereo pair for surround sound, click the button on the right speaker, click the button on the left speaker, tell the app how far away from your listening position each speaker is, and you’re done.

    We watched a lot of movie clips with the Play:1 speakers proving the left and right surround for our newly created 5.1 home theater system, and they did a great job. Sync, as far as we could tell, was perfect. The Play:1 speaker is more than capable of reproducing surround effects well and with precision and clarity. Adding them to the back of the room totally changed the game. We added surround sound without running speaker wires, we did it with the click of a button, and we did it without the popping and crackling you can get from a wireless speaker solution.

    Drawbacks

    The biggest drawback is the single optical audio cable. The first, and most obvious, is if you have multiple sources, like a cable or satellite box and a Blu-ray player. In that case you’d still need something else to switch the audio for you so you didn’t have to manually switch cables to change inputs. The second reason is that optical cables simply don’t support the latest and greatest audio codecs. Sonos may never support a 7.1 system with four Play:1 speakers in the back of the room, but an HDMI input and support for the newer audio codecs would go a long way to making the Playbar feel more future-proof.

    Conclusion

    After the review, this was one of the very few products that Braden’s wife asked if they got to keep. Unfortunately not. And unfortunately it was too late to pick them up for Father’s day, but there’s always Christmas. She asked because of how dramatically better the sound was on the loft TV using the Playbar. It was like night and day. And the speaker is so slim and well designed aesthetically, that it blends right in to any media room setup. There is so much more that the Playbar can do that we haven’t talked about. It really is a great piece of equipment.

    Bottom line, if you have Sonos, get a Playbar for your secondary TVs. If you don’t have Sonos, get your feet wet with a Playbar and before you know it, you’ll be adding Play:1 speakers all over your house. If you watch a lot of movies on those secondary TVs, get the Sub and the extra two Play:1 speakers. You’ll be impressed, and so will any guests you have over.


    Podcast #638: Slingbox Sharing Jun 06, 2014

    Slingbox Sharing

    You know we are fans of the Slingbox (Buy Now $265) and have used them to “Sling” our local TV from one side of the world to another. Ara spent a week in India and never watch a single minute of local television opting to watch football from the USA instead. Slingboxes are quite simply the easiest way to watch your local content wherever you want, provided that you have an internet connection.

    This got us thinking, wouldn’t it be nice if we could watch other people’s local content. Say you want to watch news from say Chicago or Seattle, a Slingbox makes that possible but what are you going to do? Set up A slingbox in every city you may have an interest in? No, of course not. But you do have a few options:

    AmericanTV2Go.com

    With AmericanTV2Go you actually signup for a DirecTV subscription of your choice and are provided a dedicated Slingbox to access it with. You pay for the DirecTV subscription just as you would if you were living in the states. Then you pay an additional $80 a month for the hosting service. That service provides you with:

    • A top-of-the line Slingbox

    • Unlimited upload bandwidth

    • A second network address for your DVR - This enables remote scheduling of recordings and access to over 7,000 On Demand shows and movies

    • The ability to reboot your system instantly, 24/7/365, via our easy-to-use self-serve system

    • Customer support

    This service is probably best suited for the expat who wants to stay connected with the US. If you want to watch the American football you can purchase the Sunday Ticket package for additional fees. No word on local channels but they may be available for the Virginia beach area. Virginia Beach is the home of AmericanTV2Go.com.

    Live American TV

    LiveAmerican.TV is similar to AmericanTV2Go but rather than using DirecTV they use cable services. The best we can tell is that you get a Comcast or FiOS account. LiveAmerican.TV offer customers a fully managed Slingbox hosted television service from New York City and San Francisco. There is no hardware to worry about as LiveAmerican.TV hosts and maintains all the equipment. Your account includes a DVR box as well as a Slingbox when you sign up. No other fees are necessary.

    • VPNs - Watch shows normally reserved only for viewers in the US, wherever you are in the world. $5/month or $45/year.

    • DAILY RENTALS - Any San Francisco package tailored to your needs including MLB Extra Innings, NBA League Pass, NFL Sunday Ticket, NBC Sports Live Extra or BeIN sports. $8/day

    • PREFERRED HD - Local (San Francisco Bay Area), news, entertainment, sports, kids, travel and non-stop music channels. 300+ channels. $90.00/month.

    • PREMIER HD - Same as Preferred HD but with thousands of hours of on demand content, Playboy TV and tens of sports and movies channels. Add a 100-hour dual-tuner DVR for only $10/month extra. $120.00/month.

    • ULTIMATE HD NYC - Over 300 channels in total. Includes the most High Definition channels available. All movie channels like HBO, Starz, Showtime etc. Includes Dual Tuner HD-DVR so you can watch all your shows anytime. All NYC local and Sports channels. Full access to all Free On Demand that FIOS offers. SPECIAL - Only $149.99/month.

    Slingsharing.com

    You can try and roll your own by using forums that join Slingbox owners from around the world. Slingsharing.com is one of those site that has two thousand members from around the world. The way it works is you read the forums that grouped by regions, USA, Canada, Asia, Australia, Europe, and South America. People are either looking for or offering Slingboxes for viewing. Typically its a trade. I grant you access if you do the same. It seems fairly safe, just be sure not to give out your administration password. You may want to avoid this if you have bandwidth caps as someone can really rack up the bits if they are constantly on it.

    We see a day when content will be available to the entire world simultaneously. That may be a few years away. But for now Slingboxes are the best way to bring the world closer together! Now lets all hold hands and sing Kumbaya.


    Podcast #637: Glasses-free 3D projector concept May 30, 2014

    Glasses-free 3D projector concept

    Nothing says “the future of display technology” like holograms. If you’re a Star Wars or a Star Trek fan, you know that someday we’ll have holograms for real, interacting with us. But until now that notion has existing only in science fiction and our imaginations. But fueled by the same dreams you have, over the past three years, researchers in the Camera Culture group at the MIT Media Lab have steadily refined a design for a 3D video technology that doesn’t require glasses at all.

    The MIT group believes their concept has the potential to provide a cheaper, more practical alternative to holographic video. And they don’t think it’ll take decades to get there. They’re using a technique called multiperspective 3D, which is quite different from the stereoscopic 3D technology common in homes and movie theaters. So this isn’t stereoscopic 3D without glasses, which some of us have seen and not been impressed with. This is a completely different approach.

    Watch the video

    The MIT researchers have built a prototype of their system using off-the-shelf components. There’s nothing exotic about the system, so the cost shouldn’t be prohibitive in mass production. They also built a prototype of a new type of screen that widens the angle from which their projector’s images can be viewed. The technology will be unveiled at this year’s Siggraph conference in Vancouver this August (Aug. 10-14, 2014). Siggraph is the major international conference in computer graphics and interactive technologies.

    Much like the holograms in your science fiction imagination, objects depicted by a multiperspective 3D display actually show different perspectives as the viewer moves about them, just as the objects would in the real world. While stereoscopic 3D tricks your brain into perceiving depth that isn’t there, multiperspective 3D draws a visual representation of the object from multiple angles, providing more of a “floating” image than a perceived depth. Next step: the Holodeck.

    How it works

    We encourage you to read the full news release at mit.edu for all the details. We’ll do our best to present a summary of what they have put together, but we certainly aren’t MIT researchers, nor do we try to play them on the podcast.

    The projector uses two liquid-crystal modulators, which are essentially tiny LCD displays, positioned between the light source and the lens. The first LCD is used to adjust the angle of the light passing through it. So the video information (which is the the light passing through it) reaches the second modulator only at particular angles. The combinations of the patterns displayed by the two modulators enable a viewer to see slightly different images from different angles.

    “For every frame of video, each modulator displays six different patterns, which together produce eight different viewing angles: At high enough display rates, the human visual system will automatically combine information from different images. The modulators can refresh their patterns at 240 hertz, or 240 times a second, so even at six patterns per frame, the system could play video at a rate of 40 hertz, which, while below the refresh rate common in today’s TVs, is still higher than the 24 frames per second standard in film.”.

    Added bonus: Better contrast and resolution

    It turns out that passing the light through the two modulators can actually improve the contrast of ordinary 2D video as well. We all know about the challenges LCD displays have had representing true black, and one of the reasons we lament the loss of plasma as much as we do. The problem stems from the fact that a little bit of light always leaks through even the darkest regions of the display.

    One of the MIT researchers, Gordon Wetzstein, explains it like this. “Normally you have contrast of, let’s say, values between 0 and 1. That’s the full contrast, but in practice, all modulators have something like 0.1 to 1. So you get this ‘black level.’ But if you multiply two optically together, the black level goes down to 0.01. If you show black on one, which is 10 percent, and black on the other, which is also 10 percent, what you get through is 1 percent. So it’s much more black.”

    Not only an improvement in contrast, but by changing the way the two modulators are used, you can actually heighten the resolution of the resulting image. If the patterns displayed on the modulators are slightly offset from each other, you can spread the pixels so that the the light passing through them will interfere with itself in ways that produce a higher resolution image. As you can imagine, the team at MIT has come up with a way to calculate the patterns needed on the modulators to produce that effect on the fly, in real time.

    The MIT team believes these two factors could make the technology an excellent bridge for theater operators - even before there is content available to take advantage of the multiperspective 3D capabilities. They can install projection systems now that provide better contrast and add the ability to produce 4k images (using only two 1080p modulators) and then they’ll already have the multiperspective 3D technology sitting there. Sounds like a win-win.

    Movie - 4.0 Stars (out of 5) Review

    Lone Survivor is a gritty realistic movie based on real life action heroes in the Navy Seals. The movie does a great job of showing team brotherhood and the banter between them is entertaining and engaging. The tension and action feel real because you actually care about the characters and you know what you are seeing really happened. Just to prove how real the action is, several times during the movie my wife screamed, "No" at the TV. The movie has one of the best firefights I have ever scene on film. Not only did it sound amazing, but it was directed in a manner that made you feel like you were there. Overall, the movie is action packed and heartbreaking, but it’s a good monument to the tough men who fought in "Operation Red Wings".


    Podcast #636: Emotiva UPA-700 Seven-Channel Power Amplifier May 22, 2014
    Show notes

    Emotiva UPA-700 Seven-Channel Power Amplifier

    One of the best thing about producing this podcast each week is knowing that our listeners go on the same journey that we do. Our current journey is that of separates. A few weeks ago we reviewed the NuForce AVP-18 processor and MCA-20 Amplifier (Podcast #631). This week we continue the journey by reviewing the Emotiva UPA-700 Seven-Channel Power Amplifier (Buy Now $499).

    The UPA-700 is ideal for those wanting to move into separates without breaking the bank. When you consider there are single channel amplifiers that sell for more than $1500, you may ask, how good can a seven channel amp that costs one third the price actually sound? Well we’re here to tell you pretty darn good!

    Features:

    • Seven-channel amplifier 100 watts / channel (4 ohms; all channels driven) 80 watts / channel (8 ohms; all channels driven)

    • Advanced engineering with short signal path class A/B design topology.

    • Top quality parts and construction.

    • Real power on tap to easily drive complex loads.

    • Heavy duty power supply with oversized toroidal transformer.

    • Gold-plated five-way binding post output terminals.

    • 15mm solid milled aluminum faceplate.

    • Channel status LED’s.

    • Stealth mode (status LEDs and Standby button halo lighting can be switched off).

    • Remote trigger input and output.

    • 115 VAC or 230 VAC with automatic detection and switching.

    • Full protection from all common input and output fault conditions.

    Setup:

    Setting up an amp is truly trivial. You connect the speakers, power, pre-outs, and the 12V trigger from the receiver. If you have your speaker wires on banana plugs the whole thing takes three minutes! At that point you can power on the receiver and go. But you know its never really that easy.

    The UPA-700 was connected to a Pioneer Elite VSX-94TXH receiver. The Elite is 125 watt beast that has served Ara well for a few years. He has been quite happy with the sound but now that we are exploring separates he was willing to try the $500 amp that has been highly recommended to him by Ray Coronado (SoCal HT Audio/Video Calibration and Consulting).

    With the 12 volt trigger connected to the Elite the 700 is supposed to turn on when the Elite is turned on. This was not the case. It turns out that the Elite must be told to trigger the 12 volts per input. Once the settings were updated all was good. The UPA-700 was glowing Blue which let us know everything was good to go. By the way, if you don’t want to see the Blue power light or channel LEDs you can turn them off with a manual switch on the back panel. The last thing to do was to rerun the auto calibration and then we were off to the races!

    Performance:

    As stated earlier the VSX-94THX already sounded quite good and we were not expecting a big improvement in audio quality but we were hoping for something. What we found was crystal clear audio that brought a smile to our faces. We listened to intricate classical pieces that spanned as much of the frequency range that we could find. Lows and mids sounded incredible. the highs were a bit bright but that could be the EQ. Ara’s go to classical piece is Beethoven’s 9th Symphony "Ode to Joy”. The triangles are what he keys on and they sounded like they were right in the room with you. We listened to Rock and Roll from CD and Blu-ray. You could hear each instrument clearly regardless of how loud we were playing it. Movies were another place where the amp shined. Dialog was crystal clear and effects seemed to come alive.

    In all its not like we could say that the UPA-700 was x% better than the Elite. It was more like we had a better listening experience overall. The Elite is a very good receiver and the UPA-700 is at the lower end of Emotiva’s line so the fact that we heard any perceived improvement speaks to how good Emotiva’s amplifiers are. If you were going from a lower end to mid tier receiver our opinion is that you would hear a bigger improvement in audio quality.

    Another area that has concerned a few readers/listeners is that the UPA-700 is only 80 Watts. Understand that Emotiva rates their amplifier with all channels running simultaneously. Some manufacturers only rate their system with two channels. For Ara’s room which measures 16 feet by 20 feet the UPA-700 could overpower the room. Sometimes people feel more is better and in many cases that is the truth but in this case more is just wasted. For the record the 125 watt 94THX will produce less than 3dB more sound than the UPA-700 and the human ear will barely be able to hear a difference. If you have a larger room Emotive also has a three channel amp (XPA-3 Buy Now $799) that puts out 200 watts. you can run your surrounds off your current receiver and put the front wall on the XPA-3. That way the speakers that get the most use with the most important material have the best amplification.

    Conclusion:

    There is no doubt in our minds that a good AV receiver is a great way to listen to your music and watch your movies. But when you are ready to take your experience to the next level, separates are the way to go. If you are in that in-between stage, mating the Emotiva UPA-700 to your receiver with pre-outs will get you the best of both worlds. The UPA-700 provides the biggest bang for your buck upgrade to your typical AV receiver.


    Blu-ray Review #76: Concert Videos May 20, 2014

    Music to Show Off Your Theater

    We received an email from Martin who asked us to take a look and listen at the Dave Matthews and Tim Reynolds concert that is available on Blu-ray. According to Martin: The sound is astonishing, like you are sitting right there. I have heard many concert discs but this is something else. Shows off my system even better than a pacific rim or transformers.

    Dave Matthews & Tim Reynolds: Live at Radio City Music Hall [Blu-ray] (2007)

    We totally agree with Martin’s assessment. So we thought it would be fun for one episode to pick three concert Blu-rays and discuss them on a show. All six will put you right in the middle of the concert and will make you happy that you invested in Blu-ray!

    Adele – Live at The Royal Albert Hall

    Audio: DTS-HD Master Audio 5.1

    Even though this concert is performed in front of decent sized crowd, it sounds great and still feels intimate. Adele has an amazing voice and this Blu-ray captures it perfectly, it almost sounds better than the studio recording. There isn’t much subwoofer action, but the audio is extremely crisp and clean.

    (Buy Now $24.87)

    Alicia Keys – VH1 Storytellers

    Audio: LPCM 5.1

    This concert has a small crowd and has a very intimate setting. Colorful curtains and backdrops set the scene for Key’s soulful music. The low-end is tight and sometimes even vibrates the couch. Her voice is sometimes sounds strained and a little congested but she still gives a solid performance. However, the star of the show was listening to her play the piano. The room was filled with every keystroke and making it more of an experience than just watching a concert.

    Foo Fighters – Live at Wembley Stadium

    Audio: LPCM 5.1 (48kHz, 24-bit)

    There’s nothing like being a huge concert. Screaming crowds filled with energy and loud blaring rock music. This Blu-ray is the quintessential rock concert captured on Blu-ray. The Foo Fighters have so many hits, this concert runs 2 hours long and even had a special appearance from Jimmy Page. The audio performance isn’t the best though. Vocals are a little echoy and muffled, low end is a bit muddy, however this is what most rock concerts sound like.

    The Eagles - Farewell Live From Melbourne

    Audio: DTS-HD Master Audio 5.1

    If you like the Eagles then this Disc is for you! Not only do you get the classic Eagles you also get the best from the band member’s solo stuff. The concert was in 2004 so no need for restoration. Just crystal clean audio and video. I couldn’t help smiling through the whole thing. Audio was clear and tight! My favorite by a long shot!

    Heart - Live

    Audio: DTS-HD Master Audio 5.1

    This was a Soundstage concert made specifically for DVD/Blu-ray which made me leery of buying it. I was worried that they wouldn’t bring the energy. Fear not! The ladies brought it and put on a great show that included their classic songs as well as some great Zeppelin covers. The video was good quality but the audio put you right in the middle of the audience. Mixed with the music coming from the front and crowd from the surrounds mad for an enjoyable disc.

    (Buy Now $9.99)

    Dire Straits - Alchemy (20th Anniversary Edition)

    Audio: DTS-HD Master Audio 5.1

    I bought the Album and recorded it to cassette. Then I bought on CD and played it over and over again. I had never seen the concert but I knew it like the back of my hands. Seeing the concert made me so happy as now I could accurately imagine the scene. Unfortunately the video was 4:3 and not really the best. It was still better than SD but not on par with the other discs on the list. The audio wasn’t as good either. But it was certainly as good or better than the CD. I think I enjoyed this disc the most even though it was not technically as good as the others. That just goes to show you how powerful music is! It should always be enjoyed in the highest quality you can find!

    Podcast #634: Interview with a Broadcaster about Aereo May 08, 2014
    Show notes

    Interview with a Broadcaster about Aereo

    This week Ara spoke with a broadcaster from the Birmingham AL about the internet streaming upstart Aereo and how their model is essentially to steal content from broadcasters and sell it for profit. For those who are not familiar Aereo is a company that lets you record and stream local television in the cloud. More info about Aereo available on their website.

    Broadcasters feel that Aereo should be considered like a cable or satellite company and pay retransmission fees. Aereo says they are renting equipment to capture free over the air content that is available to the public. The Supreme Court will hear this case which can have major impact to how we receive our entertainment in the future. Will the broadcasters take their programming off the public airways? We’ll have to see.


    Podcast #633: Use an AVR for Pre/Pro or a PreAmp? May 02, 2014
    Show notes

    Use an AVR for Pre/Pro or a PreAmp?

    We recently reviewed the NuForce AVP-18 all-digital HT dedicated preamp/processor (MSRP $1095) paired with the NuForce MCA-20 multi-channel amplifier (MSRP $1995). Our goal was to compare the performance of separates with the performance of a high quality AVR to see how they’d stack up. We used to hold the position that for just about everyone, the AVR would be more than good enough.

    In may be an overstatement to say that we did a complete 180 on our position on separates; but we have certainly changed our tune. While the all-in cost of the NuForce setup would run a cool $3090, and is a tad higher than we’re used to paying for a self-contained AVR, the performance and quality are there to back up the price. Is it worth it for everyone? Of course not. Is it worth looking into if you want great audio quality? Absolutely.

    Not so fast…

    But wait, many modern day receivers actually include PreAmp outputs so you can bypass the internal amplifiers altogether and run the sound through an external amp like the NuForce MCA-20. Essentially turning the AVR into simply a dedicated Pre/Pro (Pre-Amplifier / Processor). What if you already had a Receiver you loved and you could simply run the audio through an external amp - would that give you the best of both worlds?

    We decided to put that question to the test in a follow up to the NuForce review. We again stacked the Pioneer VSX-1120-K and the Denon AVR-3806 against the AVP-18, but this time used the same MCA-20 for all comparisons. What would it sound like if we simply used different processors to do the same job? After all, they’re all converting the same audio formats, like Dolby TrueHD or DTS Master Audio, from digital to analog, so shouldn’t they all be roughly the same?

    Background

    We’ve heard people claim in the past that any processor decoding dolby digital is going to sound the same as any other processor performing the exact same job. Of course we know this isn’t true, but it is a common belief. There are even those who believe all amps basically sound the same. But that’s like saying all 300 horse-power engines are alike. We know this simply isn’t true. For all of the cases. But could it be closer to the truth for some than others?

    Results

    The results didn’t really surprise us. Please keep in mind that we review according to our perceptions - according to how we hear the sound with our ears. The tests aren’t scientific as much as they are anecdotal. Your mileage may vary. But if you forced us to choose a hypothesis before beginning the experiment, it wouldn’t have been too far off from what we experienced.

    Bottom line, both the Denon and the Pioneer sounded better when using the external MVA-20 amplifier. We tested using the same Klipsch Reference and HSU Research speakers as the last comparison. The Denon sounded the best of the two receivers, but we felt like the Pioneer actually got the biggest boost in overall audio quality from the test. To our ears, the Denon starts out sounding better, and it ended up that way as well. The Pioneer, however, either has lesser quality internal amps, or was able to do a better job running the external amps, and it showed the biggest improvement.

    But, when it was all said and done, neither the Denon nor the Pioneer sounded better than the NuForce - to our ears at least. They were closer, and actually in many areas harder to distinguish differences than the last round, but still not quite as good. In the spirit of openness and honesty, Braden was so impressed by the first round of NuForce review that he decided to acquire the pair for use in his own home theater. It’s entirely possible his ears were experiencing a little bit of irrational exuberance as a result of the purchase.

    But removing any irrational exuberance, the final conclusion makes logical sense. A device purpose-built to deliver the best possible audio experience for the price outperformed the devices engineered to pack as many features into a price point as possible. Yes, you sacrifice features by going with the dedicated PreAmp, and yes it may age out a bit quicker as a result of that. But from a pure sound experience, it was top notch.

    Conclusion

    If you have an existing home theater receiver with PreAmp outputs, will you get a sonic benefit by pairing it with an external amplifier? In our limited experience, yes you will. The amount of difference you get is based on the processor itself, the amps it has bundled internally, the amp you choose to pair it with externally, and the speakers you’re driving with it. But is it a good first step toward dedicated separates? You bet it is.

    There are trade-offs to any home theater upgrade or investment. Some will produce higher dividends than others. You have to weigh all the factors when choosing where to invest your hard earned cash. For some, moving to separates, or even baby-stepping there by running an external amp with your existing receiver, is the next, right investment. for others it isn’t and it may never be. For many out there listening that killer receiver you just bought is great, and it’s all you’ll ever need. for those who know it could sound better, there are options for you.
