i was thinking of upgrading. I'm using a Onkyo sr700 as a pre pro w/an ADCOM amp right now. i was wondering if there will be a noticable differance in sound if i was to upgrade to a dedicated SSP or maybe a new receiver with a better DSP. i know alot of new receivers come w/dual 32 bit chips and DENON uses the 32bit sharc, any differance vs. my single 24bit chip. also a THX certified SSP/receiver might fit the bill. what do you guy's think.
