Hi Toga, if you can get a Memphisto on a deal in your price range, short of the Boulder 3060 I'd say your search ends there. In that price range the 2160 would be on my short list, especially in the context of synergy with your Ref 40 pre. Vitus also has great synergy with Magico, though Vitus power amps are best matched with a Vitus pre for best synergy.

If you pm me your email address i'll email the technical white paper for the 3050 mono's. Btw, Rich hasn't finished the white papers for the 2100 series as yet. His biggest issue is getting access to units to take digital photos. The 2100 series amps are based on the same architecture as the 3000 series, so it will still offer much insight.

Cheers,
