Siddh..I don't have experience with Jadis but I did once own and love a Cat SL1 MK3..and with careful tube rolling
you can probably get sound you are looking for from it..to my ears, the CAT was revealing but not analytical as some people say, very neutral presentation, not overly euphonic, a very hard peice of audio to critisize..the Ultimate can only be better..there are some who say that the pre and power should be of the same manufacturer..if I were in your shoes, I'd pick up a used CAT Ultimate (there is one on auction right now) before selling the Jadis and compare them side by side for a month or two, if the CAT dissapoints (which I doubt), you should get most or all of your money out of it.
