I know there is the Extreme upgrade, and then there is the better red circuit board. There are a lot of Extremes out there with the older green boards.New Extremes I know come with said red board. Anyone here kept their monoblocs in the standard single transformer configuration, but upgraded to the better red board? Klaus told me he really likes the sonics of this configuration. Anyone care to comment on the sonic improvements of the red circuit board? Thanks in advance; I've read all 48 pages, didn't see this specifically discussed. The reason I ask is, I have a standard pair of monoblocs (actually Klaus has them @ this moment), and would like the best sonics possible, but would like to keep the power consumption reasonable, since I do leave 'em on 24/7, and I know the Extremes draw more juice.
