I have a Dennon 3802 w/5 Paradigm Studio 20's v2 and a PSW1200 paradigm subwoofer. My room is 16 X 12 or so. In addition, I am considering upgrading to 6.1 sound soon(by buying another pair of studio 20 v2). Would buying an amp significantly improve my performance? The two I am looking at are the Rotel 1066 and the Rotel 1055. The salesman said he thought the 1066 wouldnt make much of a difference, but that the 1055 would really make my system shine. Now, I do realzie that the 1055 is only 5.1 so I would have to run the 6th channel off the Dennon. Anyways, bottom line is would make it a big enough difference to justify either the 699 or 999 price tag? P.S. As a side note, my hope is get a much cleaner sound, not a "louder" one.
