Holoaudio May (Level 3) D/A processor
Back in the digital Dark Ages of the 1980s, R-2R "ladder" DACs acquired a bad reputation due to their poor linearity at low recorded levels. The advent of sigma-delta DAC chips in the early 1990s, which didn't suffer from this problem, seemed a godsend, though ladder-DAC lovers continued their advocacy on sound-quality grounds. I was a sigma-delta guy until I heard the ladder-DAC HoloAudio May (Level 3), which, with its combination of superb measured performance and sound quality that, as Herb Reichert wrote, "makes every…

Something's Coming

So, what's "this thing of ours"? I'm only half-kidding. High-end audio is deadly serious for many passionate audiophiles. Some measurement types defend their turf without thought—without mercy—and often deride subjectivists, like me, who believe if you like what you hear, then that's what counts, enjoy. Objectivists say if you can't measure it, then it doesn't exist. Well, goes the retort, you don't know what to measure, your instruments aren't refined enough, and on and on.

The struggle continues to this day for some reason, and boy-howdy is it ferocious, especially regarding cables.…

Bowers & Wilkins 705 Signature loudspeaker

Back in June 1994, I reviewed the Bowers & Wilkins John Bowers Silver Signature standmounted loudspeaker. This speaker cost a breathtaking $8000/pair at that time, and I subsequently bought the review samples and their matching slate stands. It was the best-sounding speaker I had used in my Santa Fe listening room: When the company's then-owner, Robert Trunz, visited me a couple of years later, he told me that he hadn't realized how good the Silver Signatures could sound. But after I moved to Brooklyn, in 2000, the Silver Signature never worked as well in my new listening room. I still…

Bowers & Wilkins 705 Signature loudspeaker Page 2

With their ports open, the 705 Signatures reproduced the 1/3-octave warble tones on Editor's Choice with good power down to the 63Hz band. While the 50Hz tone was quieter, the 40Hz and 32Hz tones had reasonable weight, the latter aided by the lowest-frequency mode in my room. The 25Hz and 20Hz warbles were inaudible, but there was no audible "chuffing" from the port with these tones. With the ports blocked, the 63Hz tone still had effective weight, but the 50Hz and lower-frequency tones were suppressed. Opening the ports again, the half-step–spaced low-frequency tonebursts on Editor's…
