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.

In my experience and in general you need to move up the food chain $ to get more resolution that is what you pay for. I went from a cj PV-10 to a cj premier 16ls II and better resolution was one of the improvements along with better frequency extention.

Tubes sound different than ss so that is something you have to decide you want. But a tubed pre with ss amp is a great combination at least in my experience.

And as others have said something is wrong with your PV-10 as mine was very quiet.

Oldnslow: I bought a C-J PV-11 here on Audiogon about 4 years ago. Not sure when they started, but I have had some issues with it. First, like yourself, I get an intermittent high-pitched whine or whistle out of one channel. After two re-tubes (one done by myself, one done by C-J), I still have this issue. I think it is tube related, since moving positions on the tubes moves the whine. Second, I have a fairly pronounced channel imbalance. It is big enough that the PV-11's balance control is not always able to compensate. This is also variable, and seems to deteriorate as the PV-11 warms up.

A year ago, I sent the unit into C-J for a retube, repair of the channel balance issue, and check-up. Although C-J is pleasent to deal with, they could not reproduce the channel imbalance in their lab. The unit got a clean bill of health from C-J, but the two issues persisted after the check up and retube.

Although I found the PV-11 to be very musical and detailed, I was not willing to make any more attempts to repair it. I decided to go in another direction, which so far seems to be a success. However, I did stay with a tubed pre. This is the only tubed component in my rig, and I feel tubes provide a certain musicality that a 100% SS system cannot. YMMV, but before you commit, try to audition whatever $2K SS preamp you have in mind in your system, and judge for yourself. If the PV-11 did not have these two issues, I could have lived with it for many more years. It is quiet (for a tube pre), dynamic, detailed, natural sounding and fairly extended. That said, my replacement preamp offers even more detail, a better soundstage and more bottom-end extension.

If you are willing to spend the money to use RHB Design's services, perhaps they can do a better job than C-J itself. I considered it, but the idea of taking a big, non-reversable chance that RHB could fix everything and improve the PV-11 appealed less to me than just getting something a bit better, with none of the issues of my PV-11, and add some long-desired features as well.

Let us know how you make out!
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!
