It's all up and running ghetto style. I have a DIR9001 receiver, PMD100 digital filter, and the PCM63P-K DACs. Many thanks to Pars for hooking me up with -V reg to get it going.
So far I think it sounds very very good. I plan on letting it burn in for about two minutes to two years then compare it to the Buffalo.
I might also look into adding a external clock and upgrading the analog PS caps.
