Question about optimizing performance.....

As you can see from my signature, I just recently upgraded my system to lsi 9's as fronts, lsi c center and lsi fx's as rears. I HAD rt55's in front, cs400 center and fx300i's as rears. I am running the pioneer elite as a pre and the b&k av5000 as my amp. My question related to optimizing performance. I am wondering if the amp is 4 oh. Stable first of all. Secondly, would it be better for performance to bigamous the 9'sa nod run the center with the open channel. Then run the surrounds off the avr. Right now I have one channel on the amp assigned to each speaker. Any suggestions on how to get better performance? If the amp isn't 4 ohm stable am I harming anything or should I upgrade?
As always, thanks I and acne for any suggestions you have.
Take care,
Shawn

Looks like my amp isn't 4 ohm stable according to this chart. http://www.bkcomp.com/fileadmin/content/bk_support/FAQ/Previous%20Amp%20Specs.pdf
How much harm am I doing running this setup with my amp?

Don't be sad; it's really my own fault. Should have researched before doing it. Now I will just have to upgrade the amp as well.Shawn

You are not doing any harm unless your really cranking that amp. Emotiva amps are 4ohm stable

B & K are pretty stout amps. I think you'll be fine unless you really get on it.

Thats all good to know! Might keep using it then and use as an excuse to eventually upgrade the amp. Looking at the sherbourn in the flea market - its local to me and hoping to hear back from the seller.Shawn

Been monitoring the heat of the amp (it typically runs pretty warm). Not anything so far that seems to be running hotter so I am not really worried about it...........yet. Thanks again all.Shawn

Well, that particular model of B&k amps is on the light side. If you like the sound, then hit up the bigger more current throwing monsters in the B&k line up. After that, experiment with different cables, maybe have Trey do the crossovers, or even take a look at the LSIM's which are easier to drive than the 9's.
Also, source components can go along way in improving performance, that's obvious. But I can tell you I have the same receiver as you and it's a huge limiting factor, particularly the pre amp section.HT SYSTEM-

I would love to be able to do all those things. Right now all the pocket change went into upgrading the speakers. Have my eye on a few amp that will drive them better but content for now. Will sell some gear and see if I can fund a new amp or better pre amp, etc.Shawn
