CD Player/Transport Reviews

There's a retro, Heathkit vibe to the curiously capitalized PrimaLuna ProLogue Eight CD player: a shelf of glowing tubes and a chunky transformer case perched atop a plain black chassis. But on closer inspection, it seems there's much more going on here. The chassis is made of heavy-gauge steel, with (according to the manual) a "five-coat, high-gloss, automotive finish," each coating hand-rubbed and -polished. The tube sockets are ceramic, the output jacks gold-plated. Inside, separate toroidal transformers power each channel. Custom-designed isolation transformers separate the analog and digital devices, to reduce noise. The power supply incorporates 11 separate regulation circuits. The output stage is dual-mono with zero feedback. Audio-handling chips include a Burr-Brown SRC4192 that upsamples "Red Book" data to 24-bit/192kHz, and one 24-bit Burr-Brown PCM1792 DAC per channel. Only the tiny silver control buttons (on the otherwise hefty faceplate of machined aluminum) betray a whiff of chintz.

US composer Morten Lauridsen's Lux Aeterna is one of the indisputable masterpieces of the 20th century. John Atkinson has recorded the male vocal group Cantus's performances of Lauridsen's O Magnum Mysterium (on Comfort and Joy: Volume One, Cantus CTS-1204) and Ave Maria Dulcissima (on Cantus, Cantus CTS-1207). (And great recordings they are—one engineer chum thinks JA's Cantus recording of OMM is the single best-engineered choral recording he's ever heard.)

At a "Meet the Designers" panel discussion at the 1992 Los Angeles Stereophile High-End Hi-Fi Show, I asked a group of successful digital designers (footnote 1) each to state how much of a digital front end's sound quality they believed was due to the transport, digital processor, and interface between the two. There was virtual unanimity: Nearly everyone agreed that a digital processor accounts for about 50% of a digital source's sound quality, the transport 30%, and interface 20%.

It's easy to be impressed by Simaudio's Moon Evolution Andromeda Reference CD player. Everything about it oozes quality and luxury, from its imposing two-chassis configuration to the multi-component disc clamp of machined aluminum. Even surrounded by my double-decker VTL amps, VPI HR-X turntable, and Ferrari Fly-yellow Wilson Audio Sophia 2 speakers, the Andromeda was usually the first thing guests asked about: "How much does that cost?" The answer is $12,500. The Andromeda should look impressive.

In the ongoing debacle that has been the introduction and promotion of high-resolution digital audio and the record industry's struggles to engage the public's interest in it, two recent events stand out.

I was stumbling through the Denver Convention Center at CEDIA 2006 when I spotted John Franks, of Chord Electronics, and Jay Rein, of Chord's US importer, Bluebird Music, stranded in the basement purgatory for "niche" products. I couldn't resist asking, "What sin relegated you guys to this little hell?"
