thinking of switching from conrad johnson......


trying to decide between pass x250.8 or plinius sb 30, was looking at the cj premier 350 or the McCormack dna 500, but these amps are getting a little long in the tooth.  any suggestion and your experience with these two amps would help.  and what pre amp would work best with them.  since not many preamp companies are left.  and any feedback from whilecamaross is very much welcomed......thanks in advance.

" preamps are c/j pv 10 and pv 12 "

That's your problem. Those 2 preamps are the very definition of dated sounding. Unless you have a really bright, harsh sounding system, I wouldn't consider either one. I had both, so I'm speaking from actual experience.
Maybe stock there would be notable rollout. Upgrade the coupling caps with cutf v-caps, all resistors and wire in the signal path and replace the diodes, and you might just ask, What rolloff? Oh not to say all the romance is lost but sure a lot more engagement can be had than that opaque vintage cj sound. I too had pv7 and pv5 back in the day. Would have sprung for the et5 but wanted a full functionality pre. If not ignore the above.
dweller tell me about the herron gear.   had a real long and good conversation with an audiogoner about cary stuff. 
Supremely musical, reasonably priced, manufactured by a true believer.
