My dear friend has recently gotten the Mini II's.Stunning speakers,and replaced Kharma 1.0's.
He drives them to a fabulous degree with Rowland 8t SS amps.To voice the system,to his tastes,he uses tubes in the phonostage only.
A wonderful set-up.I heard the VAC stuff driving the Minis,and felt it was a wonderful combo,but believe me the *t was "made" for these speakers.Magical tonality(you would not know they were SS designs)and the BASS is on another planet from what I could have ever expected from these great speakers.
BTW,at 22,600 dollars the price is approaching the limit of where this speaker should be marketed.Just my opinion,and I do think they are expensive to mfgr.
Best.
