I'm relatively new to Polk Speakers, very pleased to date, with my purchase of Rti8's up front with a Csi3 on the bigscreen and Rti4's on stands in the back. My sub is the 303 working with the 8's. My receiver is an older Sony 5.1 with 100 wpc ( package deal with cubes and a 75w sub) I also have a 202 working in the rear with the 4's (set to large). Most of my usage is HT. I thinking of upgrading my receiver to the Denon 2803 (90 wpc high current) for 7.1 with most likely Fxi3's on the side walls, or, going to the Denon 1804 (90 wpc hc in 6.1) with another Csi3 in the rear, or moving my Csi3 back and replacing it with a 5 on the TV.
Question's: Will I notice a difference with 90 high current vrs the 100 ? With the freebie 202, at my disposal, am I best utilizing it ? Feedback, suggestions on 6.1 vrs 7.1, Fxi3's vrs 5's with 90 wpc. My basement den / theater is 17L x 11W with the TV facing down the long side
