The Pace Car is fantastic stuff, Steve. It must be the best bargain in digital audio. It smokes a Playback Designs unit for digital I/O (itself modified by replacing the stock switcher with a battery supply, and replacing stock regs with Hynes units). I'll be giving my Weiss unit away to one of my daughters.
The Pace Car is currently feeding a pair of Boz (Tact) amps I've modified by replacing all regs with Hynes units, all regulated supplies with either battery or Hynes supplies, added teflon bypasses to all power supplies, replaced all internal wiring with Oyaide digital cable, etc. It's a seriously resolving system.
Thanks for a great product, Steve. There's not a hint of that annoying digital sibilance, and low level detail retrieval is the best I've heard. The music emerges from a beautiful, black silence.
