Has anyone upgraded CJ 15 to Mk II?

Per Knut, the upgrade is available and costs $575.00. Per Tor, the upgrade employs many of the changes for ART Mk II. If you have done this upgrade, could you share the experience?
I have done the upgrade. The upgrade is a new hospital
grade power cord, new tubes and a few other parts
replaced. I cant tell you about the sound inprovement
since my system had been out of service for a while
(tube rolling gone bad).
Hmm, hope your system will be in service soon. Regarding the component changes, is the power cord replaceable? Please keep us posted on the change due to the upgrade.
