FWIW I have heard the MA 12000 multiple times(4 or 5) with different Sonus Faber speakers and the results were outstanding. Whether or not the synergy(Wilson) would equal SF is unknown to me. The idea of the 462 amp is another option but I would mate it with the C 22 the extra power won’t hurt but the SQ could be a sideways move. What the MA 12000 offers is an outstanding organic flow(non mechanical) that is very difficult to achieve with any SS gear. The added bonus is not needing another quality Power Cord or IC. IMO the MA 12000 is the "Star" component in the entire McIntosh line.
McIntosh MA8950 Upgrade to MA12000?
I’m running the MA8950 with my Wilson Audio Sabrina X speakers. The combination is incredible. I had been thinking about upgrading to the MA12000 which is the highest-end integrated amp McIntosh makes. It uses a tube pre-amp and solid state amp with 350W output via auto former. Both have the DA2. Would I notice anything? I was thinking this could then eventually power the Sasha V or whatever comes in the next gen.
