>> Audioengr- So basically you're saying scrap everything and spend $20K. Sorry, not going to happen. <<
Based upon that statement alone, I can tell you're a reasonable man. In addition, you say you're quite happy with the sound quality as it is now. My question to you would be "Why mess with a good thing?"
To get sound from my PC network to my pre-processor, I'm using a LinkSys Wireless MusicBridge. I use the digital out from the MusicBridge into a digital input on my pre-pro and the sound is great. This lets me use the DACs in my pre-pro instead of the ones in my soundcard.
Using WinAmp with assorted plug-ins, I am able to playback virtually every file format - WAV, MP3, WMA, FLAC, SHN, DTS, APE.
You might want investigate using a MusicBridge, the cost is around $80 and the sound quality and convenience are very good.
