Hi I am making the transition in HT from PL to DD/DTS. I was considering getting a Denon 3802, but I am noticing some HT fanatics are using receivers as pre/pro and a seperate 5 ch amp. My idea is can I buy a lower model receiver, Denon 2802 or lower, and get a Rotel 1095 and be very pleased? I’m new at this so bare with me. How would I connect an SVS to this setup? Also with this setup would I gain an upper hand so I could keep my Polk RT 20 speaker system (wanted to change/upgrade) and not purchase a set of Paradigm Monitor 7v2 system or Studio 60 system? (cant decide). I have a PL receiver so I have to get a DD/DTS PLII receiver. Any advice would be great. You could also recommend another amp and list system cables. Oh, what does it mean to calibrate your system? Thanks in advance.
