For a long long time I've heard that there was a night and day difference between using just a receiver, and using the receiver as a pre/pro with separate amps. I am considering going this route, maybe not soon (lack of funds) but yes, eventually. But before I consider spending up to another $1,000 on HT equipment (which is on average $1,000 a year minimal habit for the last 4 years, so I'm due to spend some more ) Question 1: What degree of improvement have others seen in adding separate amplification to their speakers and useing their receiver as a pre/pro? How many times better was the sound (under any setup)? Question 2: Here is my scenerio, I am using a Denon 4802 receiver, which has a good amp section already meeting THX Ultra specs. I am considering a Parasound HCA-1205a 5 channel amp to drive the Left, Right, Center, and 2 surrounds with the 4802 to drive my 6th EX speaker (this will keep each speaker being run from discrete power supplies with 140 watts x5 and 125 watts x1). Does this setup sound good? I like the Parasound cause of the price and features. Does this change seem like it'll make a night and day difference, or at least a significant increase in sound quality that an untrained ear can clearly hear? Thanks everyone for your help and suggestions!
