Good Receivers for Infinity Kappa 7.1 speakers

Hi David I'm looking for something between $500 and $1000.  Don't have to be new but in good condition.  I prefer multichannel AVRs up to 5.1, my place is not that big to put 7 speakers, 5 is okay, the room is about 22x22 feet (kitchen/leaving/dining room).  Of course, I liked the Nak for the realistic sound.

HK990 or similar

Hi Luis,

Sorry for the delay in response - we've been slammed this past week. In that price range, your best bet would probably be either the Yamaha Aventage RX-A860 (msrp $999) or the Onkyo TX-NR757 (msrp $799). I'll send you a PM with our contact info if you require any further assistance. Take care,

-David

I would get a used but in excellent condition HT avr receiver that has pre outs on back.
Then you can get a decent sounding two channel amplifier to drive the front speakers/Kappas with.
You can use the HT avr receivers amplifiers to drive the center and rear channels. 

I have their little brothers, the kappa 5.1's and also their big brother the kappa 8.1's

These speakers aren't the easiest to drive and also aren't the most efficient thus I would highly suggest whatever receiver you get, buy one with pre amp outputs.  Then when money is available buy a 2 channel amp to power the kappas, they sound much better this way.  

These speakers aren't the amp killers that the 9/9.1 was, but they still need a bit of juice to sound good.
