Yes I used the Kharma 3.1s with a pair of Atma-Sphere M60mkIIs with great success. I tried many amps with my Kharmas (Joule Heaven's Gate, Pass, BAT VAC) and they sounded very good but not great, the Atma-Sphere was the best the group for these speakers it really brought out the best features the Kharma has to offer.
