Just for the record, I will be getting either the Outlaw 7125 or the 7500. But I am trying to decide which one will be the best for me. Also, I am a bit new to the high-end audio stuff, so please bear with me if I say something stupid.

My system is Yamaha RX-V1600 (with pre-amp outputs), Polk RTi10 mains, and Polk TC615i in-wall surrounds. I've ordered a Polk CSi5 center. (In know some of you don't like Polk, but they sound fine to me, and I wasn't about to buy MartinLogans.) My dilemma is that my in-wall speakers can only handle upto 125 wpc.

So should I get the 7500 and just power the mains and center with the amp and let the Yamaha drive the surrounds? Or should I get the 7125 and power all of my system at the lower wpc?

My system is mostly used as a Home Theater, with about 25% of the time listening to music.

Thanks in advance,
