Nelson Pass is a consummate engineer, but he got his start in physics, earning a bachelor's degree from UC Davis. As he worked on his degree, he was already an audio designer, focusing on loudspeakers—great training for a designer of audio amplifiers. Soon, in 1974, he cofounded Threshold Audio with René Besne, of audio and folk-dancing fame; their goal was to build electronics, partly because the field is less competitive—it's harder than building speakers.

If you're after an elegant classic look and a compact form factor, you'd be hard-pressed to do much better than the Luxman NeoClassic series, including the SQ-N150 integrated amplifier ($2795) and the D-N150 CD player ($2595). Both are new, and both are now shipping.

No hi-fi is an island entire of itself; every component is a piece of the system, a part of the mains.—John Donne, from The Compleat Audiophile, 1623

Around the time I took over as Stereophile's editor, I bought a Peloton, the internet-enabled stationary exercise bike. It was a lifesaver during the pandemic, when gyms were closed; despite the poor audio quality and the awful music many of the instructors choose, it's good, diverting exercise.

The most notable aspect of Benchmark Media Systems' DAC3 HGC ($2195), which I favorably reviewed in the November 2017 Stereophile (footnote 1), is its low noise floor. John Atkinson's measurements corroborated Benchmark's claim that the DAC3 is capable of "at least" 21-bit performance. While significantly less than the theoretical potential of a 24-bit data format, 21 bits is still the state of the art, and corresponds to a dynamic range—the ratio of the highest achievable digital-domain volume to the DAC's internal noise—of 128dB. That's well above the dynamic range that most power amplifiers can achieve. A good-measuring high-end solid-state amplifier is likely to have a dynamic range—the highest attainable ratio of signal to noise—of about 100dB ref. its maximum power.
