Lol, ok, I will try that reasoning out on my wife. I'm not sure if she will buy the not-so-good sound or possible distortion, but the talk about the toroidal transformer may just do the trick! She is an engineer after all.

Maybe I will do QS10's in the rear dining area and leave the QS8's on the sides in the living room area.

And you don't have to remind me about trading in equipment. I'm really good at justifying expenses to myself :-D But, I will hit you up when I need help convincing myself that I need omnidirectionals!
