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?

I have a Sonograph SA-250 (I see there is one for sale on this site right now) and although I have not used it in awhile due to equipment swapping, in my opinion it is a very fine sounding amp.  I believe this is a Mosfet amp.

I think the Sonographe amps unlike the c-j MF ss amps used bipolar devices.  Though sounding slightly different, both were very good. Either one might be preferable depending on the rest of the system.

^Perhaps I should have said earlier c-j MF ss amps. I believe the latter ones use both mosfets and bipolars.
