Luc, your post is a bit unclear and perhaps has led to a misunderstanding in the earlier replies of what you're proposing. You say that you have two 5960s and you seem to be indicating that you want to connect one to the other(not buy a separate amplifier). If this is what you have in mind, then no, this can't be done with the two 5960s since the second one doesn't have a direct input to its amplifier section, and even if it did you can't run two amplifiers in tandem one after the other and add their power together.
sorry for the confusion but you got it right. Since I got a good deal on the yamaha receivers I wanted to know if it was possible to chain the two receivers together instead of buying a seperate amp (which is expansive). I thought we could plug the pre-amp outputs (rear speakers )from the first amp into the multi-channel inputs of the second amp (for the rear speakers).

Yeah Luc, that's what I suspected. But on the question of more power capacity, unless you're exceeding the capacity of your 5960 now(possible but unlikely)spending money on a separate amplifier would be just a waste of money. There's no magic in separate amplifiers and unused capacity is simply that: unused.

There's another angle that we have to consider.
The SPL out of speakers doesn't climb indefinitely. Just because the M80s are rated to 400W, that doesn't mean they don't saturate from an SPL stand-point well below 400W. All the power that goes into them after saturation simply gets converted to heat in the voice coil and filter network. And the room saturates as well. So I don't understand what the "extra" power buys anyone?
And the other question is what does that 400W really mean? I bet I can easily put 400W of complex power into the M80 with my cheap Denon that is rated 90W/channel. At 50Hz (the frequency at which the M80 experiences its impedance minimum), my Denon need only source about 7.5 Amps (real + reactive) which I'm sure it can do. Now as to what it sounds like at that level is an entirely different matter.
I think I'll try this tomorrow to see what happens.

Luc,
You can't chain amps the way you were thinking. You can hook them up to separate speakers but like Johnk and I have said, you don't need to for your situation.

I'm not using all the power of my receiver. I rarely crank the volume over 1/3.

There you go. Take the other Yammi back or use it in another room.
I use less than a watt on average for music and a few watts for movies.

What you are suggesting is feasible Luc and a good use of both receivers now that you have them. I have done the same setup on several occasions using combinations of amps and receivers for different speakers to free up amp headroom. Your instincts are correct in wanting to keep more power on reserve for the speakers. The net result will be greater dynamic range with less distortion during loud passages and transients and less chance for clipping.
Chaining two receivers is not as good as having a second separate amplifier because you will be running the surround signal through a similar circuit twice. However, depending on how well Yamaha designs its analog circuit it likely will not sound much different.
A better alternative to consider is to run two digital outputs from your player, one to each receiver and hook the mains to one and the centre/surrounds to the other. This configuration also allows more flexibilty with bass management through setting different crossover points among the different speaker groups. It also means you don't have to turn on both receivers if you just want to listen to stereo mains. And though I am not a fan of auto-equalization, it may also help with setting equalization, YPAO, in the Yammies. You should still run the analog connections for DVD-A sources.

I will keep them, all three. I have two HT rooms (one yamaha in each room) and I had a great deal at FutureShop for a brand new Pionner AVR for my computer @150$ CDN (it's a model from last year).

OK, maybe I'm missing something, but wouldn't the only effect be to use the (identical) amps in the other Yamaha instead of the (identical) amps in the first Yamaha? That doesn't get you anywhere.

Assuming he has wired them properly, if he uses a Yamaha receiver-amp with one set of speakers and another identical receiver-amp with the other set, he will improve the systems sonic qualiies compared to just using one amp for all speakers. He will have created more headroom with more power on reserve. That typically means improved dynamic range and less distortion especially in transients.
Two amps are sharing the burden of all the speaker load instead of one.
