Hello Steve, I have heard all of the amps you mentioned on your exact speakers. Allthough my system is nowehere near the highest level I am constantly improving when and where I can. At the time, those(N802s) where the speakers I was building towards. Anywho, of the three, I found the Pass to be the best suited for my taste. It is very nuetral. It has possibly the most inner detail in the midrange that I have ever heard. Along with very articulate and controlled bass, and sweet airy highs. A highly refined and resolute sound. If my budget allowed I would have one in a minute.
I am currently seeking a Bryston, 6B-SST or 4B-SST, I havent decided which. The 4B-SST is very similar in sonic qualities to the Pass, nuetral, a little more pronounced bass, very close in the midrange detail, but just not as refined. Which of course is to be expected at about half or less the cost.
The CJ amp, in my opinion has a totally different sonic character. It has an overall "warmth" while the others seemed nuetral. The bass was excellent, the mids very soothing, and the high end detail was less pronounced. It too, didnt have the resolution and refinement that the Pass exhibited, but nonetheless a very nice sound at its price point.
I would strongly recommend autioning the Pass and the Bryston before purchase. However, I agree with N2twochannel, if you like your MF2250, then its bigger brother will probably staisfy the N802s needs without much overall sonic change.
