dam! i kinda wanted to take baby steps LOL. i was hoping i would see improvment going up to the denon 3310. wow,....okay then. i'll look into the 4310

one more question though. just to get it right. there will be no Sound Quality difference from the 607 and the 3310, but there will be with the 4310. is the 4310 that much better in Sound Quality versus the 3310 or is it just added features like networking which i don't need? thanks jake!!!
