CAT JL-2 amp upgrade


I have a CAT JL-2 power amp, version 1. I know there is an upgrade to version 2. Has anyone had it done? What did it cost? How long did it take? What were the results? Thanks for your input.

Thank you for responding, Wadia 150. By your comment, I assume you had the upgrade done. May I ask how much it cost, how long it took, and the sonic differences you noted between the JL-2 version 1.0 and version 2.0? Did you keep your JL-2 after the upgrade or change amps? Thanks.
