Well he did do the Liquid Lightning. More correctly he ripped off the stax srm323 and used mosfets for the output stage.
But alex will say that all circuits look the same after a while.
I doubt the Liquid Glass is that complicated. Alex calls it a mu gain stage. completely open loop. capacitor coupled
to a mosfet output buffer. a single tube with a pair of triodes per channel. no matter how hard you try to match the two tubes
you get channel gain differences.
I'm sure the liquid gold schematics will show up eventually. People will be in shock and awe of its greatness.
