Any experiences with the Mcintosh MC901 monos?

Hi all, I was wondering if anyone had any experiences with these gorgeous amplifiers? Prefarably from owners, but also if you heard them at a show, at dealer,…

If possible also share with what speakers they are paired, and in what configuration they work best for you (with the crossover, overlapping, crossover bypassed etc)

I saw them once at a dealer and was absolutely in love with the design, but unfortunately they were not hooked up yet, so I did not have a chance to hear them…
