Rookie Pre Amp Question


I know this is a newbee type question, but I am hoping one of you will take the time to answer it (please use simple language!).

I am running an H/K AVR 335 as my receiver in my 7.1 system. I am running Athena AS-F1 towers as mains, AS-C1 as centre, AS-B2's as surrounds, and S.5's (small bookshelf) as rear surrounds.

I have an AVR 230 that I am not using. My question is this. Is is possible to use the AVR 230 as a pre amp, and is it a good idea?

If used as a pre amp, does the power from both receivers get sent to the speakers (double the power?)? Or is it only possible to use one power source at a time? If the power doesn't stack or double (terminology??), then this is just a dumb idea and I will leave my system as is. I am trying to get more power on the cheap. If the power does double, would it be advisable to use the AVR 230 as a pre amp to the mains, centre, and surrounds or just to the mains or to the front three?

If anyone can advise me on how to hook this (if advisable/feasible)up I would appreciate it. As well, any opinions/advice on any of this would be appreciated.

Thanks in advance,
Derek

He would need pro-outs/amp-in option on at least one of the receivers...pre-out on the other at the least. I gave this some thought (very little though) because these options are not likely at these receivers price points, and...very complicated for a newbee.

One of the pre-amp sections would need to be taken out of the loop.

I thank you all very much for your quick responses and help. I don't need more power, I was just being greedy and trying to learn a little. I am running an HSU STF-2 sub, I forgot to add that to my first post. The system is actually more than adequate for my needs/wants. I am realy enjoying this sight and I appreciate that you people took the time out of your day to help a noob.
