Dynaudio Contours with Conrad Johnson 2500a

For some silly reason Conrad-Johnson refuses to give specs of power output other than into 8 Ohm loads, at least for their solid state products. Then they advertise that some particular models put out 1/3 more into lower impedances. 1/3 more than what? I really wish they would change their policy. I'm sure many people discount their products because of it.

The Conrad Johnson MF 2500 was reviewed in Stereophile and when it was tested, it produced 450wpc into 4 ohms.

Pettyfeversk - I initially was driving off two channels of the five channel KAV-500 at 100w/ch into 8 ohms. I upgraded to drive it from the two-channel KAV-250 rated at 250w/ch into 8ohms. I am now using the FPB-200c rated at 200w/ch into 8ohms. All three are rated to double in power all the way down to one ohm.

Both upgrades were very significant. The sound was nice with all, but there's no going back having heard it with the better amps. It's a much fuller sound, and gets up and "moves" without having to be as loud to get the feeling. The Krell and the Dyns are a nice match, IMO.

If the CJ goes from 250 w/ch into 8 ohms to 450 w/ch into 4 ohms, it might well work. Certainly sounds like it's worth a try if you want to go with the CJ.

Would not recommend Classe with Dynaudio. Dynaudio tweeter is very revealing, Classe does not have enough finesse on top end to sound musical and refined. Pass Labs, BAT, CJ, or even McCormack will do better. CJ 2500A should have more than enough power unless you are in a huge room.

One CJ owner claims his 2500A sounds better than Krell 350MC which he also owns. CJ makes very musical gears and that applies to their SS gears. Older McCormack is more musical than newer model, but older units have more reliability issues.

Hey Pettyfeversk,

I agree with Perkadin about the Sim Audio with the Dyns. I first heard the 3.0 with the W-5 and it was a very nice match. I own the 1.3MkII and I drive them with a Plinius SA-250MKIV and they sing. The Plinius goes 250wpc and doubles down. Very smooth but authoritative sound. They make a very nice combo. Good luck and happy hunting........John
