I would agree with the above, get an DAC for between your computer and Pre-amp.
My question is why three channels? Which three channels are you running?
I see you have a three channel amp but what speakes are you using?
With out knowing exactly what your goal and budget is, I would buy a good DAC, even maybe something like the Marantz music Network player, or pioneers has something similar. And then run that in to a good tube Pre-amp, find a good used Audio Reseach LS-16 or if you have the money there are quit a few good Pre-amps out there.
Then I would hook I up via 2 channel and do you best to setup the speakers correctly and you should have a great sounding system. But remember, I am not there and I don't know what your exact desires are when it comes to the end result so no guarantees are given.
I hope this helps a little.
