I just sold a classe ssp 600 and bought a parasound c2, sonicly I hear no difference, both sound great compared to the japanese prepro's, I would recommend the c2 over the c1 as I found the touch screen on the ssp 600 useless from across the room, unless you have it sitting right next to you, I don't use the video processing as my video sources are hooked directly to my tv using hdmi 1.3, I use the digital outs for audio, I bought the c2 to match my parasound amp, good luck
