CJ:MF 2300,MF 2500A or Evolution 2000?

I'v owned the MF 2300, and I now currently own the MF 2500A. The 2500A is much better then the 2300. It has much better detail in the midrange and its much smoother sounding. The 2500A is one of my favorite solid state amps. The 2500A is also better then the 2500. I'v not heard the Evolution 2000. But here's 3 posts about it. http://forum.audiogon.com/cgi-bin/fr.pl?aamps&974249055&openfrom&1&4#1I

The 2500A is the best way to go, there is no comparison (so to speak) with the older models. Their new products reflect numerous upgrades, better components and new technology. The end result is a better sounding amp. Clean, fast, detailed, everything you would expect from CJ. They will introduce a new SS amp soon. You may want to wait and listen to that and then compare.

I second Doug99's comments pertaining to MF2500A being much better then the 2500. I had mine upgraded about a year ago and have been very impressed with the improvement.The amp has no problem driving my Thiel 3.6's.
