Channel D/Pure Vinyl & Pure Music
OK, it's a bit more involved than that but essentially that's what it took to convert Dire Straits from LP to 24 bit / 192 kHz files. The Pure Vinyl software requires some hardware as well in the form of an Analog to Digital converter. Rob was using his own Channel Seta D Model L Ultra Wide Bandwidth 5MHz Phono Stage ($3,800) with the Seta RCM Analog RIAA Correction Module ($1,200) for the task at hand. One important aspect of Pure Vinyl which Michael Fremer talks about in his review is the fact that RIAA equalization is done in the digital domain through Pure Vinyl. Here's one relevant quote, ''…And don't be surprised if that's what happens, particularly if you pay attention to the digital RIAA's finesse and robust attacks—particularly in the bottom octaves—and its unerring tonal neutrality. You know the old audiophile chestnut of the lifting of veils from the music? Listen and that's what you're sure to hear, without an additive penalty in terms of the usual digital edge and etch."
If you continue to read all of these room reports (and if you do - thank you and I'd like you to try a little experiment. Set your stop watch, hit "Go" and try to read every single room report in under 10 seconds. That will give you some idea of what it's like to try to cover a show as large as RMAF in about 20 hours including beer-breaks), you'll see that many manufacturers chose to demo their Mac-based computer audio solutions using Chanel Ds Pure Music software ($129). The rest of the gear that we listened through in the Channel D room included the Apogee Duet 2 192kHz Firewire ADC/DAC ($600), the lovely Frank Schroeder-designed Artemis Labs SA-1 turntable ($8,000) which housed a Kuzma 4Point tonearm ($6,500) and an Ortofon A90 MC cartridge ($4,600). Amplification was handled by a Hegel H21 ($6,500) and while I was in the room a pair of Polk Audio RTiA5 monitors ($350/pair) were in use.
I will also take this opportunity to point you to the Channel D website's excellent Getting Started with Computer Audio page.
