Adcom GFA5500 2ohm stable? & house wirinig

yea... used is what I plan on doing!!

Room size is 13 across x 21 long with 8ft ceilings. 15ft of one side opens up to another room & about half of the back wall opens up as well. My girlfriend is moving in with me & we are combining stereo's.

Presently she has a 10yr old yamaha receiver (my denon is 16yrs old) which will be upgraded in a year to something.... cross that bridge when I get there. My speakers are better then her's so we are using these....

Main speakers Infinity Kappa 8.1 vII's
Rear surrounds Infinity Kappa 8.1VII's
Center Infinity Kappa Video (& I hope to do 7.1 with same Kappa Video's on side of room)

each front Kappa 8.1 will have a parasound amp powering it & the rear 8.1's will share a amp. Not sure the model but around 200w per channel (girlfriends amps).

Sub-not 100% sure on what I will be using, we are redoing my house & not sure exactly how much room I have to work with. Either a pair of 12's or a pair of 15's is what I want to use.

hoefully that helps....

Well, it really depends on what subs you're getting. You could consider powered subs, which would be better than subs and the Adcom.

There was a posting here a while back by a woman who bought B&W 801s and was disappointed with the bass. She was running them off an Adcom 200 wpc. Everyone suggested getting a "better" high- current amp. She did, and it changed everything.

It's not all about wattage when it comes to amps. There is a difference.

Are parasound amps any good? I thought those amps are better then my adcom so I was planning on using those to power my speakers. Would I be better off to purchase a new/used amp to run my kappa 8.1 main speakers.... & then do a sub at a later date? Or use the parasound amps for the subs & all surround speakers & buy something better for the mains..... ??

I was planning on trying a pair of Image Dynamics IDQ drivers however a few people have steered me to 15" Tempest-X or th 12 in Shiva-X which they claim will perform better & cost me less. I am not sold on buying a prebuilt sub enclosure/amp due to how small the enclosures are & also being stuck to whatever amp is provided. I am trying to determine how much room I have to build a box & also waiting on the new specs for the tempest-x that is suppose to be released in a few weeks.

I also thought I could always try my Adcom & when I can afford to get something better for the subs I could upgrade at a later date? I thought giving my main speakers the best amp is my best bet....

Yes, I do prefer Parasound to Adcom. I'd stay with what you have for the mains and surrounds.

I also would not rush into a sub until you're sure what you want. A homebuilt is a great idea if you're hand - there are plenty of designs out there. Another option is to use the Adcom on the surrounds and use the Parasound on the subs.

Yea, I am definantly not rushing into it. I have a friend who is going to make the enclosure for me (he's doing the entire entertainment cntr) & when I know how much room I have to play with I will then decide on which sub.

I guess I will have a better idea when the amps are hooked up what I should do. I have also heard great things about bryston amps & finding one of their amps used might be a option but due to their cost that will be a while.

That is a good idea though, using my adcom for something else..... like if I do end up with 7.1 they could be used on the kappa video's.
