I use Slimserver with a fully RWA modded Squeezebox 3 connected to a MHDT Paradisea tube DAC via cheap glass optical cable in my living room rig. I also use JRiver Media Center with my notebook and an Edirol UA-25 in my bedroom rig. All my CD's were ripped to a Simpletech 160 gig external HD using Itunes and lossless then I discoverecd JRiver. This is still a work in progress and I'm not sure where its headed. Unfortunitely my pc and laptop are down so I'm forced to use my cheap sony DVD player connected to the Paradisea tube dac. With all honesty the DVD player and dac sounds pretty darn good.
Enjoy.
