So, I'm all set up here for hi-Rez surround 5.1 from SACD, DVDA and BluRay. Also, I run my CD collection ripped flac through a laptop as a server. I first want to say that I was having some trouble getting the sound from my server to match a physical disc. Out of curiosity, I ordered 2 Audioquest Forest USB cables, one between my hard drive full of music and laptop, and the other from the laptop to my external Asus Xonar U7 sound card. From that I go digital coax to my receiver. Anyhow, today I got one of the cables, the one for the hard drive, and let me say to those of you who don't think USB cables can matter, they do. Instant improvement so...either something was wrong with my cheap cable or it really does matter. Either way, I'm convinced and looking forward to getting the other cable tomorrow. Hopefully it will improve things a bit more. Maybe the cheap laptop will cut it after all. My best sounding Hi-Rez: King Crimson Thrack on DVDA XTC Oranges and Lemons on BluRay Talking Heads Naked on DualDisc DVDA Elton John Captain Fantastic on SACD Nine Inch Nails The Downward Spiral on SACD Beatles Love on DVDA (not for the purist, but sounds excellent) And I have about 40 total surround albums and most sound pretty amazing. The Who, Quadraphenia, Rush 2112, Moody Blues EGBDF, Dire Straights Brothers in Arms, etc, etc.
