Pros/Cons of moving from CJ PV 10 to SS?

With your description of preamp,it seems to have a problem.Had no such symptoms with mine.There's an Airtight ATC1 that finished at auction with buyer unable to proceed.Its available for 1455$.Great history and new tubes.It was 6K 5 years ago.That would be a winner.Other than that lots of great pre's here for 2K.Good luck,your going to be happy real soon with what you have,Bob

Pro you will likely end up with a cleaner sonic going SS. You will almost certainly eliminate the high pitched sound, but as mentioned that is suggestive of a physical problem with your pre that should not exist. You may want to get it fixed. The rest of your system sounds fine and with 6 Moon's little shoot out comparing two First Watt amps with the M designed to have a wqarm sound, the Cullen Wyred was found to be even warmer. Yes look it up! I would be careful going overboard with Vandy's. So its a pro for a more middle of the spectrum synergy if you use a crisp SS pre, with the rest a little toasty.
The con, and it's a big one, is the potential loss of stage, air and halography, which is what I always found was the great beauty of tubes. I would suggest to fully appreciate this phenomena try an all tube system with pre and power tube amps. It's quite a revelation. Too me it was, anyway.

I would strongly suggest you at least contact RHB Dezigns who modifies cj and other hi-end equipment. They are real pros. and design their own circuits to maximize the original preamp. They modified my cj PV-12L and the openness and smoothness is amazing. I have met Bob Backert. He is a true gentleman and committed to making the most of your gear.

why through the baby out with the bathwater would suggest you get a used ARC 100.2 that has a nice 100 k input imp and your existing CJ will fly with the Vandersteen 3A sigs.
and you will be hooked without wondering about your Music
