Isolation stands: snakeoil?

@lalitk hate to break it to you but digital equipment is just as susceptible to vibration.

Just this morning I tried swapping a set of <.5mm constrained layer damping sheets below the base under my master clock (this is a 10Mhz clock that drives the system clock in my DCS stack) -- the effect was quite audible (and in this case negative)

Surprised no one has brought up active isolation (herzan etc) -- you can see the measurable impact via the pics in my virtual system

@jbrrp1 I'd missed your post, sorry

btw have you tried changing the power cable on your Herzan? Shouldn't make a difference but it does! I've only gone up to a $300 or so cable, I can't find it in myself to go further (although maybe I'll try if I liberate a spare from the rest of my system)

@john_g its about 8-9’ from speakers to listening seat. A near field configuration but the walls are all designed and built to minimize issues so it’s as if the front wall really disappears
