Somebody, if I can remember djk mentioned that adding regulated power supply for the voltage gain stages of Leach amp would make improvement in sound.
Further investigation showed that McIntosh and Electrocompaniet are doing something like that...
Has anyone done that on Leach amp?
Recommendations?

The supply board from the A75 is still available from:

I would use a smaller transformer for the boosted voltage, rather than a doubler.
