FWIW- I have tried many different digital separates (including jitter devices). The whole is seldom as good as the sum of the parts. Why? The basics. They all need proper isolation, proper power cords, and especially-proper power conditioning. For too long I put the cart before the horse thinking better dac, transport, jitter device, moding them would take me to musical bliss. All I did was fork over a lot of hard earned dough. By the time you add all the ancillaries up, you are easily pushing $3Gs.
Digital seems far more dependant upon high quality power than analog. The digital output sections are universally compromised, unless one is spending huge bucks, like on dCS gear. My current rig is a Sony 9000es (SACD/DVD/CD Player), a BVaudio SR 10 Sound Refiner (an absolute must), plugged into a PS Audio UO-HO, which is plugged into a B-P-T 2.5 (as are my amp/preamp, tuner, powered sub). It's about the same amount of money, but the sound is fabulous. BTW, I am getting the new version of the Xindac SACD player (<$2K, tube output) in any day, so you might want to check in with me. The build quality is comparable to Mark Levison, Krell, Accuphase, but at 1/10th the price.
