I posted a message earlier about the yamaha receiver. I'm going to try swapping the left and right channels in the pre-out main in, and that'll determine if it's the amp or the pre-amp (I think). So if it's in the amp, the actual left speaker would still sound weak, but if it's the pre-amp, the right speaker would sound weak.

If it's the amp, are NAD amps any good? What do you think of the C272? I want a good overall sound. Something that'll be better than the Yamaha's amps, drive my current Polk speakers well, but be very well matched for the Definitive Tech speakers I'll eventually get. I'm new to separates, but I like the versatility and the improved sound quality. Is there any particular amp you recommend (2 channel at least 100wpc under $1000)?

Also, if the pre-amp is bad, but the amp in the Yamaha RX-V2095, what do you guys recommend? I'm pretty lost if that'd be the case.

I appreciate the help.
Thanks!
