Conrad Johnson PV10A Mods/upgrades

Lloydelee’s third alternative should be seriously considered if resale value is of concern. Even though Bill Thalmann and Bob Backert are both accomplished technicians whose cj mods are well reviewed, the amp can only be considered a pure cj if cj does the work. That, IMO, should add to resale value. In my conversations with Bill and Bob, I came away with the impression that Bob’s mods were somewhat more invasive - not to say that the result isn’t stunning.

At this point, I would suggest that you develop a very precise set of objectives, and without initially disclosing those objectives, determine through your interviews which guy most shares your values - if he hears like you hear, he will do a better job.

Thank you so much everyone! I think I'm leaning towards Bill Thalmann.. I like that fact that he was an employee at CJ and that that will probably be ok if I ever sell either unit..
I'm excited to hear the difference!

No doubt they are all good options. Good luck and please post!!!

You may want to check out http://www.conradjohnsononwers.com. It's a forum site dedicated soley to Conrad Johnson owners. It's new but membership seems to be growing and it's a nice place to have a place for CJ owners to congregate. Also, you may want to post this issue there and get some feedbacks as the readership will be completely made of CJ owners.

I use a PV-12 and love it. I have listened to the PV-10 as a demo and it had a wonderful sound as well.

Yeah Bill Thalmann charged my friend $10 per diode to upgrade his amp plus labor. The diodes cost less then $2.00 each. Gee Thanks! Upgrades are only one way to go but just swapping out parts do not mean you are getting the best out of your equipment most likely just a change in sound.
