Hi snazzed,
Thanks for contributing but there are some mixed-up statements in your explanation of amplifier classes. lol! I'll try not to take that personally! Yeah, I know that I don't know too much about Amps... that was about as much as I could figure out when I did a bunch of research about 6 months ago. Seems to be a regular technique of mine... find people who know what they are talking about and say, "this is how I think it is..." and then learn when they tell me how I'm wrong. It sucks, however, when I say "this is how I think it is..." and nobody knows any better. Of course I then assume I'm right. I'm just glad I repeatedly said, "this is what I think and I may be wrong" humbly snazzed

Hi again,
Certainly don't take it personally. It's really complicated and I have to ask our chief engineer every time I talk about amplifier classes. There is one more class I forgot about, fairly rare, but used by NAD in their stereo amps, a Class H (or is it G--I've just had my late afternoon glass of red wine so I'm too lazy to go look it up). The NAD amps have quite modest continuous rated power output, about 50 watts per channel, but when musical dynamic peaks come along, a second set of voltage rails on the power supply momentarily switch in to generate up to twice as much power, 100 watts in this case, equivalent to 3 dB of headroom, to avoid clipping the peak signal.
Cheers,
Alan

You guys are awesome. Thanks for the input so far and keep it coming.
I have just ordered iwow M22s, iwow M3s and an iwow Vp100. I think the VP100 will do the job based on your feedback, but if it doesn't, the 150 is in the wings. I can't wait for it all to arrive. I'll be tracking it by the hour across the US from Canada!

I think I may have the answer to your inwall on wall V100/V150 conundrum..... http://www.axiomaudio.com/boards/ubbthreads.php?ubb=showgallery&Number=294434

Outlaw's M2200s are also Class G. It's a kinda neat design, considering that most listening is done with only and handful of Watts. The difference between G and H is that G has two rails of fixed voltage, it just steps up to the higher one when the lower can't deliver the needed power. With H the second rail is variable, and follows the signal providing only what's needed. H is even more efficient, but has slightly higher distortion.

I've never had a problem with sibilance out of my 150. That said if you're looking for the ultimate center channel with that system, most people will tell you the best choice is to use the same center as the mains you're using.
So three M22's might be the best set-up for you if you can accomodate it under your screen.
