Tony Stark once famously said, “We have a Hulk.” Brent and Dennis have a secret weapon much more powerful than that. We have a Floyd Toole! And this week, we sit in conversation with him about the release of the fourth edition of his legendary book, Sound Reproduction, and why it has a different subtitle this time: The Acoustics and Psychoacoustics of Loudspeakers, Rooms and Headphones.

We’re on Patreon! Find us at https://www.patreon.com/AudioUnleashed

First things first this week, Brent and Dennis wonder why Wired is doing pretty good blind panel testing when actual audio publications almost never dare, or bother. Then they have a conversation with their buddy Joe Mariano, aka Joe N Tell, about his new speaker measurement and target-curve-calculating app Magic Beans. How does it fare against Brent’s bazillion years of measurement experience and Dennis’s kazillion years of calibrating audio systems? Finally, Dennis asks Brent WTF a “notoriously musical” CD drive even is.

And for Patrons: Can Bowers & Wilkins and other former Sound United brands maintain their identity under their new Samsung/Harman umbrella? And should they?

First, Dennis and Brent take a minute to praise a Stereophile article that harkens back to the good ol’ days of audio journalism. Before the dark times. Before … well, all sorts of unsavory developments in the publishing biz. Then they peruse a number of new articles about the state of Spotify, as well as one potential new alternative that’s pretty much just Bandcamp in a trenchcoat. Next, they run a serious risk of being tagged as “garbage” on YouTube by examining the claims of a young audio pundit who’s convinced he’s smarter than everybody else in the headphone industry. Finally, they rant against a Headphonesty scare piece about audio networking until they realize that Headphonesty completely misrepresented the views of the network engineer quoted therein.

September 17, 2025“A Yankee Corndog”
We’re on Patreon! Find us at https://www.patreon.com/AudioUnleashed

This week, Dennis and Brent take a vicarious vacation to a couple of hi-fi hotels to discuss whether or not this is a trend worth taking seriously. (And, of course, judge the merits of their audio systems just by the brands.) Next up, they applaud John Darko’s efforts to make reviewing more legit, then ponder some ideas on how, exactly, we might do that. Then they venture halfway around the world in the company (figuratively speaking) of tech journo Geoffrey Morrison, who shares the ancient wonders of Tokyo’s Akihabara Electric Town while lamenting its apparent but perhaps inevitable soulsucking corporatification.

We’re on Patreon! Find us at https://www.patreon.com/AudioUnleashed

This week, Dennis and Brent gaze deep into what they assumed would be the abyss of the EISA Hi-Fi Awards and see some pretty sensible selections gazing back. Then, Brent humors Dennis by letting him rant about video game music, and the two of them dig into the mechanics of how a guy made some of the world’s most memorable music with just a few bloops and bleeps. Then, they dig deep into the sometimes glorious, sometimes sordid history of Monster Cable by way of a cheapaudioman video essay, and recount their own decades of struggle in dealing with a company that makes your average rock band look like a well-run business.

And for Patrons: What goes through Brent and Dennis’ minds when they read a glowing review of an idiosyncratic speaker? Find out in real time…

We’re on Patreon! Find us at https://www.patreon.com/AudioUnleashed

This week, Dennis and Brent do some sleuthing work to ascertain whether a crackpot article about Tom Waits is A.I. slop or just straight-up plagiarism, and whether or not Dr. Sean Olive has a substance-abuse problem. Then they sort through two lists of speakers that audiophiles all either love or hate to find which speakers are on both lists, wonder why it seems like every audiophile who’s ever “polled” must be over 70, then (sort of) fondly reminisce about the (mostly) lousy speakers from the days of their youth—many of which are on one or both of these lists.

This week, Dennis and Brent dive deep into the subject of infrasonics by way of a “studio-quality” MP3 album that tunes baroque music to the planet’s Schumann resonance and thus allows you to be calm and focused (i.e., the sonic opposite of Audio Unleashed), and they also ponder the utility of two new subwoofers bigger than our dynamic duo put together. Next up, Dennis gets a rare opportunity to critique mindless capitalism (i.e., Brent) as he heaps surprising praise on an article about politics from Stereophile, of all places. Then they opine on whether Focal’s new $69K beast truly is the ultimate speaker and the one they’d buy if they were actually able to retire someday.

This week, Dennis and Brent ponder the questions that everyone ought to be asking: Why hasn’t anyone tested speaker isolation devices before now? (Like, really tested them, not just gauged their emotional reaction to them.) Why does AI music sound so much more convincing than AI images look? (And can AI out-ButterBurger House Band the real ButterBurger House Band?) Why is Erin Hardison so damned good at YouTubing? (And why are manufacturers’ speaker sensitivity measurements so often meaningless?)

This week, Dennis and Brent wonder why Stereophile killed the comments section on their website (besides the magazine’s desperate quest to deprive Audio Unleashed of a reliable source of entertainment). Next, they speculate about how juicy a deal reviewer Cameron Oatley got for voicing Warwick Acoustics’ $38,000 APERIO GoldenSound Edition headphone system, and discuss what it might be like to have their own endorsement deal. (Audio Unleashed fuses, anybody?) They conclude by trying to figure out what Apple’s new immersive audio standard does, why Apple did it, and whether Dolby Laboratories will survive being piled on by Apple, Google, and Samsung at the same time.
