Hi.
I suggested Kharma/LAMM/Purist Audio because this combination could be your reference point even if you cannot afford it new but maybe you can used. Besides, you appear to fluctuate between solid state and tube electronics of similar level, and I can understand that. I suggested the path that I myself would take. I like both Rowland and VAC. Few amps play midrange as well as top of the line VAC yet some choose LAMM. And better Rowlands are up there in the top solid state league. Personally, if I wanted to keep Wilsons I would probably choose Rowland over VAC for better dynamics bass and scale. In any case, whatever you decide - you are to have an excellent sound.
