Nobody knows the trouble I've seen
When people talk of the "Apple tax," they mean the priciness of Apple's products—a negative that for many of us is offset by how well the company's devices usually work, separately and together. Apple, though, has rarely emphasized interoperability with non-Apple devices, and the Bathys is no exception. Focal includes only a minijack cable and a USB-C–to–USB-C cord in the box; to use the built-in DAC, I had to go rummaging through drawers for a USB-C– to-Lightning adapter. The good news: I found two. The bad news: Neither worked.

Whether it's a thicker chassis, more powerful motor, more precise bearing, more effective isolation system, or something else, the emphasis is always on stepping things up a notch or two, rather than reinventing the wheel. This obsession can result in some…

Performance: Measurements made with the Shaknspin2 speed-measuring device showed that the DG-1S was running about 0.4% fast—not terrible but a little disappointing at the price, and not adjustable (footnote 4). More importantly, the peak wow and flutter was around 0.18%, an excellent result.

After several days of casual use to get everything bedded in, I started a round of more intent listening with "Round Midnight" from Chick Corea's 1982 album Trio Music (ECM 1232/33). Right out of the gate, I heard the hallmarks of a Touraj Moghaddam design, the kind of forward momentum and…

When Ayre founder Charley Hansen passed in late 2017, Ariel Brown, who is now Ayre's vice president and chief technology officer, was ready, waiting in the wings. Brown has worked for Ayre since he was a sophomore in college. As John Atkinson wrote in his February 2019 review of Ayre's EX-8 Integrated Hub, "Brown says that for better or worse, he was indoctrinated in Hansen's way of thinking and design…

I measured the Ayre Acoustics VX-8 with my Audio Precision SYS2722 system. Before performing the measurements, I preconditioned the VX-8 following the CEA's recommendation, operating it at one-eighth the specified power into 8 ohms for 30 minutes. At the end of that time, the top panel was hot, with a temperature of 113.4°F (45.3°C). Unusually, the bottom panel was even hotter, at 144.5°F (63.1°C). To reduce the possibility of overheating, I continued the testing with the amplifier raised off the test bench with inverted ceramic cones.
