I believe my tastes have changed in regard to how music is presented. In my audiophile journey, I always preferred warmth. I loved tubes, but they have limitations. McIntosh was the closest solid state, sounding like tubes but with tremendous balls. The only other amp I have heard to provide bass similar to the MC 611s was a Gryphon Diablo 300.
I did have a Luxman 590 AXII, which was a disaster in my system. My current McIntosh system is far superior.
I believe the C12000 is a great preamp, and my recent audition presented as 'cleaner and more detailed than my C2700' albeit at a $16K cost. However, I did audition the Luxman M10X which sounded glorious. I believe the Luxman presents as the middle-ground between a McIntosh system and Soulution. Still, from what I recall, the Luxman did not provide the magic that the Solution did.
I would spend a lot of time auditioning different components to do it right the first time!
