I have Aperion 633-T 's. I made my choice based on finish. (real chery veneer of high gloss/piano finish black -w- Aperion, vs vinyl laminate -w- a wood grain "look")I will also say Aperion has the best cust. service before, during and after the sale of any company I've ever delt with (inc. Outlaw, sorry guys but you're a very close second)and I manage retail store. As for performance, I can tell you, I retuned a pair of Polk RTi8's after hearing the Aperions,you'll find yourself listening for hours on end .Aperion also has a nice powered tower option. (free shipping, no tax,30 day demo option -w- free return shipping, 1 yr trade-up option) How can you go wrong? Check out the home theater galery in the Aperion forum (through the Aperionaudio site). look at the pics of the Aperion sound room and if you look through the other threads you can find picks of how they pack their speakers for shippment (again,the best I've seen)
