I am not familiar with the Arcam CD192. Perhaps you are referring to the FMJ-23 or FMJ-33?
As far as choosing between those options, you really should give them a listen and decide how much you value the incremental improvements between models. I have a CD-92, and decided to buy it because I thought it was substantially better than the CD-72, but not so much of a step-down from the FMJ that I would regret saving the few hundred bucks.
As a final note, you may want to consider buying the units off of Audiogon, as it will be substantially cheaper to buy from here than from whatever your current seller is. It seems as if you have a trusted seller and that you're willing to pay a bit of price premium to buy from him (or her). If that's the case, then I'm not going to advise you otherwise. BUT, I thought I might as well toss in my two cents.
