You guys need to calm down a bit here, and you may be missing the point about Mick's announcment.
The issue at hand is all about 'controlling potential noise problems/mismatches with amplifiers from other manufacturers' with some further improvement in sound. It's not about current Cortese/Grange owners being somehow stuck with an inferior product, it appears that Mick's new circuit maintains the magical sound of the original circuit but at lower gain therefore better matches amplifiers that have high gain.
If noise is not an issue with your current Cortese/Grange in your system then the upgrade is also not an issue?
You are also jumping off the deep end without consulting the master first! Mick is a very approachable and helpful guy who takes great pride in his work. I am sure any of you who require the upgrade need only ask him and he'll probably do it.
