Information on the Conrad Johnson Evolution 2000?

I buying this amp on the recommendation of a friend. I will try this on my Apogee speakers. I understand that they were way overbuilt and fairly rare. I did a search on these hybrid amps from around 1990 and found very little. What are the strengths and limitations of this amp. Are there any tricks to make this amp sound its best? Bob

Electroid,
Do you use the amp currently? What type of tubes do you use in your unit? I am still awaiting the unit to arrive. I think it did not have a detachable power cord because of the unit being older. What speakers have you used the amp with? Bob

Are there any mods that are regularly done to these amps? Cap changes etc? Bob

No I don't have one but sold a few. I have an earlier CJ MF-2500 and MF-2100. It wasn't difficult to modify them to accept a detachable IEC power cord. You'll need a dremel tool. I think that this is more important than internal upgrades like caps. As for tubes I like RCA black plate 5751's.

I wonder if you purchased mine (lost it in a divorce) If so you are lucky. Great shape new tubes from CJ and had not been used in nearly 3 years. I looked into modifications and there really were none worth the time and money. For the sound, I felt it was dark however tons of punch.

i owned both the amp and preamp of that series. it was very dynamic and punchy, but lacking in bloom and richness.
