Thats bitter sweet news.
I had read "the more power you give them the better they sound".
I would get to keep either front pressence or rear surrounds...

I would actually keep both but currenty I only can run either the front or rears at one time. I should have bought a model up last year but...

It wouldn't actually be more power, unfortunately--for one thing, it's all coming from the same power supply, and for another, even with separate amps, the power doesn't sum (tweeters and mids take much less power than woofers, so they'd consequentially be using a smaller percentage at any given volume level.)

The jury is out on "the more power the better" thing. Or, I should say, there is intense disagreement on it. But I don't think you'll get a lot of disagreement that biamping internal to the receiver doesn't give you more power.

Before I started looking around at recievers I figured it was all pretty simple.
1) Don't buy cheap if you want good sound
2) Don't underpower your speakers
3) Tweak
4) Upgrade
5) Repeat

You can overdo it 3. You can definitely overdo it on 4. Try to keep the number of times you do 5 to a minimum.

BRW, you appear to have picked up some misinformation in your reading elsewhere. Specifically on the two main points you mention here, a receiver can't be used to "bi-amp" a speaker and you can't simply "give" a speaker more power.

Bi-amping by definition requires two amplifiers; a receiver has only one amplifier with several output channels. The output transistors in each channel just act as valves to distribute the required amount of voltage needed in each channel at some instant in time from the receiver's power supply section. The individual channels have no power of their own, it all comes from the limited supply available in the main central power supply. Distributing this to a speaker through two channels rather than one can't increase the power available by any amount.

As to "giving" a speaker more power, that only takes place when it's played louder. At a given loudness level a speaker uses only the amount of power for which it's designed, regardless of the amplifier. At a comfortably loud level speakers of typical sensitivity, such as the Axioms, use about 1 watt. Brief peaks can take much more, of course, but unlikely anything beyond the 100 watts or so typical receivers can easily support. Adding an amplifier with a maximum capacity of 200 or 2000 watts doesn't accomplish anything. Unused headroom is simply that: unused.

Wishful thinking indeed.
Always good news though.I'll keep reading, maybe I'll understand it a bit better by the time my color samples arrive.

All of those amplifiers share the same power supply.

Fair enough.
