But some products demand a complete revision of a system's architecture. Such was the case with Devialet's D-Premier ($15,995). Not only is this French product an integrated amplifier, with phono and line analog inputs; it has digital inputs and an internal D/A section.

I miss Sonic Youth.

Well, then, how really deeply, truly do I know any record? Does it matter? Whatever.

Here’s another list: Records that I didn’t get around to in 2012, but that I hope to spend quality time with in 2013.

Gramophone called it "the recording of the [20th] century"; Stereophile named it No.1 of the 40 essential recordings of all time. Fifty-four years after the first Rheingold sessions, there is still nothing like this history-making first studio recording—by conductor Georg Solti, the Vienna Philharmonic, and producer John Culshaw—of Wagner's Der Ring des Nibelungen, originally taped and released on LP from 1958 to 1966. The unsurpassed quality of singers and orchestra, Solti's astonishing ability to tell a dramatic story in music, the epic scope and sweep of work and performance—and the sound, as much a wonder for our own time as half a century ago—make these recordings seem more precious, their combinations of qualities less likely to ever be repeated, with every passing year.

With just a few phone calls and emails, I've managed to get my hands on the amazing Stax SR-009 headphones, and some of the world's best electrostatic headphone amps and the gear to make use of them, and set them up my demo room for a week of comparative listening.

Quite the ear opening experience!

The Mahler 1 files, available in four formats, are all derived directly from San Francisco Symphony's master, not from a copy of the SACD. The formats include two DSD formats: DFF and DSF. For those whose computer playback software or DACs are not equipped to play DSD files, 24/96 and 16/44.1 PCM files in WAV format are also available.
