Conrad Johnson MF2550, What To Expect?


I should be receiving a used Conrad Johnson MF2550  250wpc solid state amp on Friday.  I have never heard the amp or any CJ equipment for the past 20 years.  What scant reviews I have read, it seems to be on the warmer side of neutral.  This is not the SE version which is a detailed sounding amp.  I am hoping for good synergy with my Rogue RP5 tube preamp and GE Triton Reference speakers.  I am presently using an Odyssey Stratos Extreme amp which is around 160wpc.  It is a little warm sounding but I am hoping the CJ will be better in my system.  If anyone owns one, has heard one or has any opinions, please reply to post.  Do you think it is a backwards, sideways or forward move?

@stereo5 Just looked at your system. Nice rig! Did you trade in the GE 1s to get the References? BTW Agree with jfant about tube pre with SS power. So many people have found that is successful coupling.

Are you using Herbie devices under the Scout TT cones?
stereo5 I have not had the pleasure of hearing the 2550, but did hear the 2300 and then its successor, the 2500. What I loved about the 2500 was it had the "beautiful, golden" cj sound of the 2300 but they had significantly improved the bass punch and depth. I would have bought that amp right then and there if I didn’t already have a fine power amp for my system.

There is a special something about cj solid state amps. They manage that tube-like lushness but with authoritative bass. I had looked at cj’s website recently and I think I would go your route rather than the SE version if the cj house sound is what you are after. I have also heard the Goldenear 1s on an occasion and found them very clean clear transducers. The references must really be something. Congrats!

Please let us know how everything works together. Audio Nirvana?
stereo5   I'm sure Friday can't come too fast!  Anticipation.  Agree with having a back-up amp. Look forward to hearing about your experience with the new cj amp.  Congrats!
@stereo5   That's awesome!  What and how you describe it sounds about right based on my experiences with cj SS amps in the past.  They just sound right.  Your comment about the lack of upper midrange hardness is THE cj SS amp quality that sets it apart from other brands.

Now...you just get to enjoy!


@stereo5  Things should be "cooked" pretty soon.  Looks like you're in for pretty sweet sound soon!  Enjoy and revel in a purchase well made.
@stereo5   Any updates about how the cj MF2550 amp is sounding in your system?
