The PS3 is a weak link. Look into a nice multi player for 5 channel SACD/DVD-A and quality 2 channel. Perhaps a modded Denon from Underwood?
Improve my system
I got the mod bug recently but don't know where to make my next upgrade. Right now i'm running a Yamaha DSP-A1 along with the BK ref 200.5 amp. My speakers are Kef Q70's for front surrounds, Energy APS5-2 for mains, Kef 200c for center, Kef Q70's for rears. Energy microstar 12.1 for subwoofer. I'm using a sony PS3 for my bluray player. I got about 2k to spend on a new toy. What should i spend it on?
