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.

I would hope that a JL-2 or JL-3 owner who had the upgrade done would chime in with some before and after comments. I have seriously thought of this with the JL-3 Sig's but they sound so mighty good already. But if the upgrade brings on more resolution and dynamics, woo hoo, that would be awesome. Just wish I could hear the two versions side by side. Would be a lot easier to quantify the differences to determine the value added right then vs. putting that same money elsewhere in the system. But CAT products do not see a version change too often so this change could truly be incredible.
In Late 2004 I had my early model JL2 updated to the Mk II status. The biggest improvement I heard was a great reduction of noise and a much more quieter backgroud. This very postive change was apparent from the first moment I played the first tune on my table. The reduced noise level results in better transparency and more inner detail being revealed. Was it worth it, Yes in my opinion.

Note: This is not the $5000 signature upgrade which is much more extensive and costly but the Mk II upgrade from there early version of the Mk I which I believe was about $1000 at the time. A nice improvement indeed.
