Of course. NAIM are using commercially available parts. They cost $10 at retail. They haven't the money to do any of this themselves. All they're using is an asynchronous converter. I made a DAC that has the same thing in it. The trick I pulled is my DAC sends a clock to my transporter, so my DAC's asynchronous converter isn't doing any sample additions or deletions, and a local clock clocks the DAC chips directly.... so nearly no jitter, no interface problems such as the papers in this thread talk about. Beautiful. The guys that were doing any real digital processing in the old days were Wadia. And look what their stuff cost. Now it looks like others are playing with silicon a bit, but again box costs are >$10k each, and often you need 3 boxes - including one that has an atomic clock. (hahahahaah - ya now I'm sure THAT makes a big difference.) If you want to play with this stuff, about the only way to go is with an FPGA. Guys that design this stuff are kinda rare, and it's very expensive to develop. -- wayne325 ------------------------------------------------------------------------ wayne325's Profile: http://forums.slimdevices.com/member.php?userid=29916 View this thread: http://forums.slimdevices.com/showthread.php?t=70626 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
