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.

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.

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