I'm still in the process of determining what sort of components I'd like to go with. I currently am running Infinity Beta 40's and a Beta C250 as the LCR (the beta 40's are like 90 or 91db sensitivity). I was thinking about buying a receiver with pre-outs (looking aventage line) and using an Emotiva amp to power my front sound stage.
Here's where the confusion comes in, the UPA500/700 have 80 wpc and THD <.01% which seems fine...but looking at a higher-end XPA-3, it has considerably more power at 200wpc, but now has a much higher THD (<.1%). Why would an amp in a higher-end model have more distortion? Would I even notice that?
