Thanks, Ozzy. I have the CI Power supply though may consider the Boulder if I send it in for the mod. I really don't want to be without the unit as I enjoy it so much. I did pull the plug on the 192k upsampler/clock, though. (Esoteric G25U). I figured if the Combo made such a large improvement upsampling to 96k, 192k should be even better. Got a great price on it and it doubles as a clock for my Esoterix X03-SE so should be a win/win.
Enjoy your new mod. Care to report a short blurb on the improvement you are experiencing?
