I also own the 3.2's and have owned several amps with these speakers. The list includes Joule Electra Grand Marquis, Lamm ML1.1 and Lamm ML2. Ultimately, I have settled on the ML2's which easily drive the 3.2's in my 18x23 listening room.
For cabling I use Purist Dominus Rev. C which work very well. I also have auditioned the Kharma Enigma cable and it too is superb.
