I can't help you w/details about the best digital formats or software for storing music on your computer hard drive -if that is what you mean but listening from a computer is pretty easy. I'm just using an ASUS netbook. Kimber cable w/USB from netbook to Mobile Fidelity V-DAC. RCAs from V-DAC to pre-amp inputs. Warm up the amp, pull up Pandora on the netbook and listen. Can also listen to downloaded music files. Got the V-DAC & Kimber cable from Audio Advisor. Got the Asus from Amazon. Everything for around $700, if I recall. (Other computer/DAC combinations might give you better interconnect options; some folks don't like USB.)
