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

I currently have a CJ PV10 for my preamp. I’m considering replacing it with a solid state preamp around $2000. What are the pros and cons of such a move?

Reasons for the move:
The CJ doesn’t have much in the way of resolution.
I will get a high pitched whine after its been on for several hours. Its done this with all the tubes I’ve tried.

Current set up:

Rotel cd player with PS Audio Dac, w/level three Cullen mods.
Amp: Wyred ST 500 (Replaced aging PS Audio 240 watt mono blocks. The Wyred sounds better).
Speakers: Energy 22.3. This was one step down from the Veritas series. It’s a bit forward sounding. I expect to replace it with either Dynaudio Focus 22.3’s or Vandersteen 3A Signatures.

Music: Almost anything acoustic, 60’s rock.

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.

After reading the responses since my first posting I would still advise you to contact RHB Dezigns and talk to Bob or his son. These guys really get it and will tell you what they can and cannot do.

Remember, they are not part swappers. They diagnose the gear and propose solutions that can get you where you want to be.

You have nothing to lose in contacting them before saying goodbye to a classic piece of gear.

All the best!
