I have been enjoying driving a pair of Focal Sopra No2's with a McIntosh MC452 for about three years now and I do believe that the McIntosh amps with autoformers on the output stage pair really well with those Focal tweeters...so, I'd second the notion of snagging a pre-owned MC152 if purchased from TMR.
I've done business with TMR in the past, straight up people there.
