Dump the metal domed, harmonically thin 3.6's - way over-rated current hogs. Sorry, but someone's gotta say it... I can't even imagine how harsh 3.6's would sound running Adcom up front through a passive. Its frightening.
Seriously though, here's what I'd do: sell the 3.6's - some long time follower of Stereophile will buy them - and get a Coincident used that can be used with lower powered amps yet is relatively full ranged; sell the LLano because you don't need to dump all that current into the 3.6's massive crossover anymore and get a nice integrated tubed amplifier, say, a used AirTight ATM300 (since you go integrated you can take the LLano $ plus the passive $ plus a bit more and hopefully flag a ATM300 at $3500); dump the MIT and go with Goertz because you don't need the MIT to roll off the Thiels anymore (although Leoturetsky makes a good point above); if you can find any money then upgrade the CD, and only pump $ into the power when these other things are fixed. Good luck.
