Thanks to everyone who has posted so far, especially with the links. Looks like I have a lot of homework to do with finding a place to listen to all of these speakers. Also, great article about audio measurements, very similar to another one I've read.
I have another question if someone would be so kind as to explain it to me. It may be silly, but I e-mailed marantz out of curiosity just to see what they had to say about the power output of the receiver. The tech who emailed me back said that the receiver is 86% efficient when all channels are driven. What exactly does that mean for power output?
I guess I lied, I also would like to know about driving the speakers. I know many threads have said that I or whoever had asked before me will never need to drive a speaker up to its rated wattage. However, there are also plenty of threads that talk about how adding more power will give a much better overall sound. Granted I know BMXTRIX said I'm only in the wading pool and there are a lot of other things to take into account, but this was just something I was curious about and it occurred to me to ask as I'm asking about the receiver.
