I have listened to this integrated amp on ProAc speakers. They were the ones with ribbon tweeters D35R I think.
I love ProAc generally but I did not fall in love with their last products.
So I did not have a nice impression of the amp. It may be very good but 12k for an integrated of this power is a LOT of money
I would buy a MA7000 without an hesitation if I had to choose between them.
Or an ARC Dsi integrated; either the 200 or the 400 will cost less.
