Opinion Conrad Johnson Solid state Amps

I owned a MF2300. It is a very powerful, load tolerant amp. The sound is smooth and lush without being syrupy. The pace of the amp was effortless, but just a tad slow. Overall, a wonderful amp.

Yes, the Conrad Johnson MF2500 was one of the most satisfying piece of equipments I had the pleasure of owning. The soft and mellow sound just melted my ears. It also tremendous amount of punch when called for.. I had it for about 1 1/2 years, then upgraded to Sonic Frontier Mono 3, because I got a couldn't resist deal. I love the Sonic Frontiers amp. Good luck.

I have a follow-up question- has anyone directly compared the MF2300 with the MF2500, or the MF2100 with the MF2250?

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
