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?

Very nice! stereo5

The Isotek disc is excellent. You are on your way my friend. The sound will continue to improve as more playing hours are accumulated. Enjoy the music.

Happy Listening!

Alright! stereo5

you will soon have (2) amps that I am considering - Odyssey and CJ.
I have spent time w/ some of the older CJ soild-state power amps, but, not the current offerings. Do not worry about the "SE" upgrade. You can accomplish this later if as you figure out which brand has the best synergy in your system.  My go-to is Jack Tozzi at Spearit Sound in MA. He is well versed on CJ products old and new. A stand -up guy to be sure.

The Rogue (tubed) will match nicely to the CJ. The older models are pretty neutral to slightly warm to my ears. I like this combo (tubed pre and ss power). The key is going to get sonic matches on cabling. Again, Jack will be an excellent resource as well. Keep me posted, here or via pm,  as you receive and massage this amp into your system. Excited for you!
Happy Listening!
