Y’all have been waiting for it! We’re here to deliver. This week, we dig into the Tekton Design/Erin’s Audio Corner/ASR hullabaloo in the way that only Audio Unleashed can. Is Tekton founder Eric Alexander the real victim here?
With that done, we dig into an article about a guy you’ve never heard of who’s out-streaming most artists you have. What does this mean? Is it an AI thing? And in our third segment, we try to figure out what the heck the Gryphon Audio PowerZone 3 power strip thingy even is.

Hey fam! A lot of you have expressed your eagerness to hear us cover the Erin’s Audio Corner/Tekton kerfuffle and Eric Alexander’s resulting and wholly unnecessary self-immolation. Sadly, we’d already recorded the tracks for this one before that all played out! Hopefully you still dig what we’ve got for you this week.

First up: A deep dive into the concept of “everything between the Romex and the amp.” Next: Our reaction to John DeVore of DeVore Fidelity’s appearance on The Occasional Podcast from back in November. Then we check out Your Morning Coffee’s new AI-generated theme song and discuss what the heck this all means.

This week, Brent and Dennis answer questions and respond to criticism from listeners in an extended mailbag segment before being joined by Wirecutter headphone specialist Lauren Dragan for a conversation about the Harman target curve. Then they dig into a Darko Audio podcast about Total Harmonic Distortion. And for Patrons: is Masimo looking to dump or spin off Sound United?

This week, Brent and Dennis consider a set of listening tests done by the Absolute Sound on fuses. Yep, fuses. Including one that costs $595. This video leads to a series of hilariously histrionic comments from Michael Fremer, whom the Washington Post once described as the “dean” of audiophile writing. Then we report on a Stereophile column about record EQ curves by Michael Trei, who compensates for his lack of hilarious histrionics by conveying useful information. Finally, we celebrate a milestone for Steve Guttenberg, the dean (not “dean”) of YouTube audio reviewers.

This week, Brent and Dennis opine about the current and future state of physical media, including something called the SMini. They also bought a pile of audio stuff from Temu and put it to the test. Is it worth the time and money? Next up: a deep dive into Stereophile’s review of the Bowers & Wilkins 801 D4 Signature flagship loudspeaker.

This week, Brent and Dennis dig into the biggest question of all in audio: exactly how much is the jitter of your DAC destroying the inner detail of your favorite recordings? They also try to figure out exactly WTH Dolby Atmos even is and chat briefly about the current state of room acoustics.

Unfortunately, Lifewire has violated journalistic standards and basic human decency by substantially reworking this article (and many others) without Brent's permission, and most of the discussion about Toole's recommendations has been removed. However, it still includes useful tips for DIY acoustical treatment, so we're posting the link here, but please don't click on any ads or do anything to support this website.)

This week’s episode starts with a question from our first Patron: Why are headphone measurements the way they are? From there, we dig into a Dolby Atmos kerfuffle from Stereophile, and opine about whether the death of music journalism is a plague or merely a symptom of a larger problem.

Then they contemplate the societal and sonic ramifications of a new $750,000 speaker from Sonos Faber; explore some cool new audio announcements from CES; and wonder what delights the new Auracast Bluetooth technology might bring.
