As a current Kappa 8 owner everyone is giving you good advice. These speakers should not be used with Monster cable bi-wire. They just sound awful. However, they do work well with MIT cable, Slima cable and the old Tara Time and Space.
These speakers love tube power. They also like amps that can be driven into low impedance loads. The Odyssey monos sound good with them. The PS audio HCA-2 sounds good with them except beware the tweeeter can get hot if you play them loud ( think the amp is a little underpowered). Older Thresholds are also good. In my opinion most Japanese amps need not apply (except Stax). The Japanese amps are either too bright or can't drive the impedance. The Marantz Ma700 sound good with them.
I would also think the Innersound amp or a Classe would work well.
You might also try taming the wall behind the speaker with a Persian rug. Also stabilize the base. I use 50lbs. of sand on each speaker.
