WIMA bypasses on the PS capacitors, input blocker, and feedback loop shunt blocker were present in my green board Stereo Extreme and now red board Extremes. I didn't lift the board on my Stratos Plus before it got the Stereo Extreme makeover, so I don't know whether the WIMAs were in place at that time. One would think that they were, given the overall attention to detail in the product.
