Thanks for the tips. I'm narrowing it down to the DENON x2200w. Will the 95w per channel at 8 ohms suffice for the paradigm monitor 9s
On paper X2200 and Monitor 9s seem well matched.
Amp is at 95W max (translates to 0-20dBW capable)
Speakers operates between 15-200W (translates to 12-23dBW)
Speakers max sustained power is 150W (translates to 21dBW)
So Denon is well withing operating range of the speaker.
Starting at 91dB-SPL your speakers can produce 91-101 dB when matched with Denon at 1 m. In the real world at 10ft or 3 m this range will be "perceived" as 75-85 dB on a conservative side. This is the fatigue free listening range. About 80dB sound at say 30% volume is not a bad experience at all.
Unless Denon cannot produce the required current under stress (read, momentary low impedance due to content in sound tracks) you should be fine. These days AVRs have enough juice to produce current on demand. If it cannot, then you will have clipping and distortion. Before you hit this limit, AVR should go into safe mode.
Now for movies, it is a different ball game. AVRs these days do not say how many Watts when driving 5 or 7 channels. Expect it to be lower may be in the average range of 60Wpc (translates to 0-17dB) in case of X2200. Still not so bad as far as sound levels are concerned. With 5 speakers it will be pretty loud even at moderate volume. Remember AVRs are smart enough to detect how much power to pump to each channel depending on the content. So there is some pretty advanced "black magic" or real-time processing happening inside.
This is all theory. The best thing will be is to lug you main speakers L/R to the showroom and stress the AVR. It is a pain but it is worth it if you can spare a day to do so.
