Pure Music Does DSD
In Channel D's own room at Axpona, Rob Robinson demmed the latest version of his Pure Vinyl LP ripping program and Pure Music audio file player program for me. One of the new features of Pure Music v1.8 is the ability to play DSD files as well as hi-rez PCM, and to emphasize that fact, I photographed the display of Rob's Playback Designs MPD-3 D/A converter ($6500) to show that it was receiving DSD data via USB2.0.
Despite the small room, the musicDavid Elias's "Freedom on the Freeway"sounded excellent, with an analog-like ease to the presentation. The rest of the system comprised Joseph Pulsar speakers ($7000/pair) driven by a Hegel H20 amplifier. Blue Coast and 2L are already offering DSD files for download, and I understand that there are many live concerts available from tapes via bit torrent sites.
SteinwayLyngdorf
The S-Series subwoofer-satellite system ($22,100) was producing a big sound with the tiny satellites stood on a credenza against the wall behind them. Incorporating RoomPerfect correction, the speakers also use digital signal processing to produce a flat response, which Peter Lyngdorf explained allowed him to optimize the drive-units for maximum sensitivity. The two small subwoofers were placed in the room corners, with a crossover frequency (depending on the room correction necessary) around 200Hz
