Ron, you, Mike and Christian are going to be at the extreme bleeding edge of analog. You’re all choosing to ignore Dave’s explicit advice to stick with inert super stiff passive steel stand, and go active Herzan. . . .
I am taking David's advice. I am specifying and I will be ordering the heaviest (3" square box legs) stand Herzan will make. I am simply ordering a stand which has the ability to accomodate a standard TS-300 in the future if I change my mind.
The only active isolation platform I am for sure ordering is a TS-140 with external power supply for the Io main unit.
