In 2007, I spent time with Bel Canto Design's e.One DAC3 D/A processor. In his review of the DAC3 in the November 2007 issue, John Atkinson quoted my comparison of it with the Benchmark DAC1, which I called "the Swiss army knife of audio" and "one of the only future-proof source components you can buy these days."
The DiaLogue tube amplifiers from PrimaLuna have, at their heart, a clever idea of their own: an output circuit that is user-switchable between triode operation, in which the screen grid of a tetrode or pentode power tube is defeated by means of connection to the tube's anode; and Ultralinear operation, in which the screen grid of a tetrode or pentode carries a portion of the AC music signal, supplied by a tap on the output-transformer primary, in a feedback-like effort to reduce distortion and increase power. Fans of the former often report a sweeter, more tubey sound, while fans of the latter report a tighter, more detailed, more timbrally neutral sound. Audio enthusiasts are given to reporting any number of things.
Audio engineers have been doing those things for ages. Have they improved their craft to the same extent as the people who, over the same period of time, earned their livings making, say, automobiles and pharmaceuticals? I don't know. But if it were possible to spend an entire day driving a new car from 50 years ago, treating diabetes and erectile dysfunction with the treatments that were available 50 years ago, and listening to 50-year-old records on 50-year-old playback gear, the answer might seem more clear.
Before anything else, there's his musicality. No one has ever played the piano like James Carroll Booker III. If the piano is New Orleans' preeminent musical instrument, then Booker is its most talented virtuoso. A child prodigy who went on the road as part of Little Richard's band when he was 14, the Ivory Emperor, the Bronze Liberace, Li'l Booker, Little Chopin in Living Color (as he was variously known throughout his life) was breathtakingly gifted.
