Need pre-amp help for Kappa 9 & Adcom GFA-555mkii

I have a pair of Infinity Kappa 9 speakers, Adcom GFA-555 mkii amplifier, Sony cdp-cx455 cd changer paired with Soundstream DAC-1, and an Onkyo p306 pre-amp. I am happy with my system for now... especially for what I have paid (about $1200 total). But the adcom and infinity both have a very bright sound. I feel like the Onkyo pre-amp is the weak link in the system right now. Any suggestions on a good "warm" sounding pre-amp for under $400 (used prices)?

Also, I am forced to run about 12 feet of speaker wire on both sides due to my set up. Any suggestion on a good wire to run on a longer run like this?

This is my first attempt and post to help. I also have Kappa 9's and have driven them with Adcom 565 mono's for some time. I like what they offer and I am currently looking for preamp options as well. I am considering arcam to talk to my adcom's. Maybe stepping into even more power like the 565's might help. Also a sub to relieve the stress produced by the 9's. The low bass response is what draws the low impedence. Roll em off at 80 and see how your system wakes up.

Pick up a used Eagle amp for $400 - someone just had one on Audiogon. It will drive any load, and the control is amazing...even better when Russell at EKSC rebuilds it.

I'm not sure what you're running. You initially stated your driving the Kappa 9's with a mono blocked Adcom GFA-565 and further down in the paragraph, you say maybe stepping into more power like the 565's might help.

I've posted for help with my Kappa 9's. I have been using the 2) 565's to drive my Kappa 8's and they work perfectly!
I believe the problem is in the 9's and not the amps.

I read another thread where someone said they used 4) 565's to power 1 pair of 9's. I may be new to the game, but don't understand how that can be done! If you have any thoughts about running the 4) 565's to power 1 pair of 9's, I'd like to hear about it!

Thanks...Bob

Bob, if the 565's are monoblocs, they can easily be connected to biamp the Kappa 9's. One monobloc for the low pass and one monobloc for the high pass on each speaker. Connect them the the two pairs of outputs on the back of your preamp and you're good to go. I've used four monoblocs on my Kappa 9 with great success.

Mitch,

The 565's have 1 RCA jack in the rear and 2 positive and 2 negative binding posts. Now, I connect 1 pair of speaker cables to hi pass on the k-8s and the other pair of cables to the low pass, same speaker...bi-wire.

Are you saying to only run (amp #1) 1 speaker cable to hi pass, another amp (#2) with cables to low pass, and duplicate this again for the other speaker, (amp #3 & #4)?

If this is what you are suggesting, will I get more power out of the amps by using only half their capacity?

Thanks...Bob
