Well, I am in the process of exploring this area by keeping all the variables same - means, same room size (L25xW14xH8.5). Same speakers (F52s/C52/S30s/Sunfire TGA-5200/SVS PB12 Plus/PS3 as the source).
I am ordering a Emotiva XPA-2 - 140w/channel, to drive my surrounds. Wanted to have XPA-3 for 2 Mains and Center, but Emotiva doesn't have bi-wiring options for Volts/Currents. Hence, skipping that route.
I would try to find out if there is difference while I connect my Sunfire and pump 200w to the Surround, then try XPA-2 with 140w. Then will run Sunfire for all 5 channel. Finally add XPA-2 to run Surround and drive Mains and Center using Sunfire.
This will give me 4 different scenarios where all the other variables will be the same. Will post the results as soon I am done with this.
Did anyone here do any similar test so far? If yes, will compare notes!
BTW, I am getting a Revel Voice 2 to replace my C52 soon. I hope it would be fun, since I do 75% HT
