Conrad Johnson SS amps

I am currently looking for a new power amplifier to drive my Martin Logan CLSIIs (4ohm load). I am deciding between CJ's MF2250 and MF2500. I was wondering what the difference was between the the stock model and the "A" model. ie: MF2250 vs. MF2250A. I would also like to know if they can they be bridged? Would I get better results using two MF2250 amps or a single MF2500 amp?

MF 2300A is upgraded version of the amp,better sounding one.

Overhang: Thanks for that info. Does this mean that both CJ 2300 and 2300A are both MOSFET-based amps?

Has anyone else noticed the "hole" in the MF2500A's lower mid/ upper bass that was described by Overhang?

Overhang, I just read the reviews you refered to. It seems to me they were describing a leaness in the upper bass region not a suckout or "hole". In a perfect world I wouldn't recommend faults to band aid problems, but, budgets do exist and sometimes we must resort to "band aids" for the best affordable sound. I wonder if this leaness would tighten up and compensate for the softness in this region in my system?
