And for Patrons: a discussion about Yamaha’s crazy-expensive new headphone amplifier.

This week, Brent and Dennis are joined by Erin Hardison of Erin’s Audio Corner to discuss his controversial review of the beloved Triangle Borea BR03. We also discuss the merits of subjective versus objective evaluations, Erin’s pet peeves, and what dragons he’s on a quest to slay.
