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?
