PASS X600 with Kharma Speakers

Any experience with Pass X series amps driving Kharmas?
I am hoping that A-Gon member "Bamafan" will chime in here. He has the Pass X-600s and drove a pair of Midi Grands with them for quite a while as he was reviewing the speakers. He would be a good person to speak to this. In my conversations with him, he thought the combination was magical.
Use a X350 with my 3.2F, works perfect!
