Okay, I'm a beginner to the HT world, and well on my way to picking a a polk rti system with: Polk rti8's in the front CSI5 center channel fxi3's for surround rti4's for the rear a svs pb-12 sub But my biggest problem is a receiver. I know I'll need one with some type of automatic calibration, because me handling an SPL meter is not gonna bring out a good result (Plus I'm lazy). I've been hearing that the yammy is better because of its DSP, but how good is the YPAO? Will it calibrate everything nicely? Anybody that has experience with either the 5860 or the 1015 please help out.
