It's been a long while, but I think the Krell amps were KSA-50, KAV-500 (bridegable multichannel). The Krell KAV-300i (integrated) was used with my friends 3.6s for many years, and he liked the setup. However, last time I saw them, he was using the Classe CAP-151, which he likes better.
Shorter auditions with Classe amps were the CA-100, CA-150 & CAP-2100 (int).
Cabling, I don't know what my friend used. Myself Polk Cobra, Oyaide (sorry don't know the model. Very quick, but perhaps a little light in the bass), DIY twisted and braided kinda like Kimber.
