This is for a modified Digidesign 192, done by Black Lion... It sounds amazing... 16 Analog inputs and outputs and 8 Digital I/O's..What do industry heavyweights like Mike Shipley, Tony Maserati, Mutt Lange, and Butch Walker have in common? They’re proud users of the Black Lion Audio FM192, a heavily modified version of the Digidesign/Avid 192. The FM’s A/D and D/A conversion is so smooth, so rich, and so clear that Sound on Sound Magazine called it “a game changer”. We’re not talking about the usual shades of grey among high end converters; the FM192 has bass extension that rivals 2 inch 16 track tape.  It has high end response that’s velvety and uncharacteristically clear for digital audio.  Instrument imaging is pinpoint accurate, with front to back extension that few digital systems can rival.Like most converters released under the Digi/Avid name, clocking architecture is based on the standard HC49 crystals in Pierce-Gate configuration.  A/D conversion is built around the CS5381 A/D chip.  D/A conversion is built around the Texas Instruments PCM1794 converter chip, which offers improved dynamic range performance over the Cirrus Logic D/A chip found in the blue Digi boxes.  What’s nice about the PCM1794 is its on-chip conversion design as well as the way the filters are etched into the semiconductive substrate; this makes it a favorite among design heavyweights whose opinion we respect. Sadly the new Avid boxes omit the wonderful copper shielding of their predecessor; something we imagine is a cost-saving move.  Analog path in the new black boxes is not nearly as impressive as the older design, with most of the path built around the NE5532, Burr Brown OPA2227 and OPA4134.  These are decent amplifiers, but we think that better options exist.
