im on the virge of putting together my first serious hi-fi system and need help choosing a pre-amp. im gonna be running all of my music out of a computer(lossless compression) and running it out of the system via digital optical out to eliminate "system noise" from the computer case. i just need a simple stereo 2-channel pre-amp that will accept the digital optical output from my computer. my speakers will be klipschorns paired with a tube amp, probably something vintage like H.H. scott. any suggestions? i dont want to break the bank on the pre-amp but i dont want to cut any corners either. klipschorns are notoriously fussy about the quality of the signal going into them.
