Although the PS Audio BHK Signature and Ayre KX-5 Twenty preamplifiers have some things in common—eg, both are fully balanced and have both XLR and RCA outputs, not to mention the fact that both products are made in Boulder, Colorado—…

In the March 2018 issue, Art Dudley admired the sound quality of Ayre Acoustics' KX-5 Twenty preamplifier, but didn't love some of its operational aspects (footnote 1). I've staged this Follow-Up as a putative face-off between the Ayre and my current reference preamplifier, the PS Audio BHK Signature, which I reviewed in the June 2017 issue (footnote 2).
To briefly summarize the controversy: Nirvana's management, Gold Mountain, and their record label, Geffen Records, were not happy with the band's choice of Albini as engineer. Although Albini had only spoken with Kurt Cobain, Dave Grohl, and Krist Novoselic on the phone, all went well when at last they met, at Pachyderm Recording Studio in Cannon Falls, Minnesota, and recording proceeded with ease.
"The studio portion of making that record was effortless," Albini said. "We were done and dusted in 12 days. Everybody was happy as clams. The process of making that record was absolutely…

Brooklyn, 1979: Fridays were fierce. After a week of doing construction, I would gobble Wild Turkey at the Spring Lounge, then fall asleep on the F train with a fold of cash and a Sony Walkman stuffed in a chest pocket of my paint-spattered Belstaff Trialmaster jacket. Usually I missed my York Street stop by only a few stations, but occasionally I'd wake up at sunrise on Saturday at the last stop: Coney Island. I didn't mind. It was restorative to shuffle the deserted boardwalk, listening to the Ramones' Road to Ruin or Television's Marquee Moon.

Focal Clear vs Audeze LCD-X: Audeze's easy-to-drive, 20-ohm, 103dB/mW LCD-X headphones are my real-world reference cans. They and Sennheiser's HD 800 S headphones—both models cost $1699—are the ones that Focal's Clear, at $1500, needs to beat.
My experiences with the venerable HD 800 Ses are limited to trying them at CanJams, but the not-always-comfortable LCD-Xes have spent more time on my head than have any headphones other than the Koss Porta Pros. I cherish the Audezes' lively, blues-with-a-feeling dynamics and the burnished-toned way they reproduce the sounds of violins, guitar…

"Okay, all you high-rolling audiophile know-it-alls—what is the argument against amplifiers that operate in high-bias, class-A, single-ended mode, with the lowest possible parts count? Is there a better strategy for beauty, rhythm, color, texture, and easy-flowing musical verity? I think not. And please explain: Why has mainstream audio gone to such ridiculous and expensive lengths to avoid building and selling precisely these sorts of amps?"
It was I, your humble prattler, who in October 2016 posed that rhetorical question, in my review of the First Watt J2, a 25Wpc power amplifier…
I wish you could have heard how physically present and emotionally intimate the Rogers 65V-1 made Buddy Holly's Down the Line: Rarities (2 CDs, Decca B0011675-02) feel through the DeVore Orangutan O/93s. The sense of Holly's physical presence was so captivating that I fell into a Holly listening binge that has yet to end. I'm infatuated with his famous Apartment Tapes, recorded in December 1958 in the living room of the Manhattan flat he shared with his new wife, Mar°a Elena Santiago, only weeks before his death at the age of 22.
I didn't need golden ears or laboratory meters to…
