As a McCormack fan, I would normally say go with McC.
But, as you have the Adcoms, why not upgrade them at MusicalDesign and see if you like them?
I had the Adcom 555 running while my DNA-1 was being upgraded by SMc. When the DNA came back, I was very pleased, but I have to say that old 555 really held its' ground for a 35 year old machine. As you say, the Adcom is kind of rough around the edges, so when I asked Musical Design about the upgrades, he said it gave it more smoothness to the midrange.
For the 555, it was quoted around $300, for the 565, probably a little more. But, that's alot less than the $1800 I paid to upgrade the DNA-1.
You haven't mentioned your interconnects. Those can make a big difference in the midrange, as well.
