CJ MF2200 or Threshold CAS-2?

I have owned each of these amps and used one or the other in my main system for many years. Though I have enjoyed them both, the time has come to part with one of the two, so I would appreciate inputs from the group on which I should keep. The prices they would each fetch are NOT a concern, but rather which is best for my current listening. That said, I have also dabbled with the thought of selling both and going with something completely different. The counterpoint is that retirement and having a smaller listening space leave me with less interest in experimentation than in my younger years. In addition to the amps, here is my current set up: Supratek Chardonnay tube preamp (has built in phono stage), Golden Ear Triton 7 speakers. Sources: Michell Gyro TT w/ Rega arm and Zyx cartridge (90% of listening), Revox A-77 R2R, Cambridge Audio CD. Eye candy: Mac MI-3 

Anyone care to weigh in with an opinion?
