Just to wrap this thread up.
I got the speakers installed(much easier than I expected) and tried them with the Nakamichi SR-4a & the Carver receiver. They were both good & the Carver tuner section was slightly better in my house, but I liked the sound of the Nakamichi better. So I'm keeping it and selling the Carver. At this point I'm listening to, and really enjoying, mostly 192 bit internet radio stations. Although I have done some listening to full-size files from my computer, and the combo of the in-walls, the Nak & the full-size files sound much better than I would have ever guessed.
Thanks for all your help.
