Macallan25, you might also inquire at the OTL Asylum. A fair number of Atma-Sphere owners check-in there: http://www.audioasylum.com/forums/otl/bbs.html

Ralph says the enhanced power supply regulation now in the Mk.III version of the preamp is a huge improvement, but this would be a factory update.
.
Why would you want to? Rushton is right, though. The upgrade by Atma-sphere to the Mk. 3 version should result in a noticeable sonic improvement. I just had some upgrades done to my MP-3 preamp, and the results were very impressive!
Another thing to remember. If you get an upgrade from Atma-Sphere you get a brand new warranty!
It doesn't get much better than Atma-Sphere OTL's ;^) Unless of course Ralph has an upgrade, cut to the chase, call Ralph. Happy Listening!
