I have compared a MF2200 to a MF2500 (the 2250 is a slightly beefed up version of the 2200). The 2200 is a very sweet and musical amp, beautiful timbres, mids, wide soundstage, a little soft i.e. slow on transient attacks (mosfet mist?), and with my 4ohm bass drivers, a little weak in the LF, not quite as much punch there as I would have ultimately liked. The 2250 may be better in that regard. The 2500 didn't sound that different but had better bass control. C=J gear has a family sound, even the ss, always musical and on the warm and rich side of neutral - not a criticiam, just the way they sound to me i.e. pretty damn good. My speakers are Alon Vs and require beefy amps with plenty of headroom. I ultimetely ended up with Meitner monoblocks. Which of these C-J amps will sound best in your system may be dependent on the impedence curve and power handling capabilities of your speakers. Good luck
