Townshend Pods under TT Don’t Do

Really curious to try and understand what is going on here.

If you look at how the Minus K works, the chassis of the device itself is quite massive (I have the big bench top version). There are these vertical upside down pendulums that are holding the inner suspension in place but allow it to sway and the spring pushes the suspension plate from the bottom. It’s a pretty ingenious design, but is costly and has its detractors who prefer other methods.

I guess my point is that it is not simply a set of springs.

A used Vibraplane is always a sort of cheap possibility (a fresh air compressor from Silentaire will set you back under 1k US new, maybe even less if refurbished with warranty). My biggest concern (which @Syntax said was a non-issue) was that the Vibraplane would require me to constantly readjust my Airline linear arm when the platform rebalanced itself on the automatic/compressor models. There are, I believe, models that allow you to manually pump the air bladders as well.

After some discussion, I found that the Herzan wasn’t really meant to address footfalls and required a pretty solid foundation to start.

Barry Diament (sp?) was a big advocate of the bicycle tire  inner tube in a homemade plinth approach-- never tried it.

Would love to own a custom Minus K!

Same effect as sitting on a waterbed! Remember those? The best base for a TT is a rigid platform. Either light or heavy mass! I have my Ariston RD11 on a 18" x 20" pane of 1/16" glass supported by four 1" hardwood cubes.

Yeah well I figured I'd try it and fail. When planning the plinth I didn't have the footfalls, then had to move house and now I do. I can definitely attest to DJ turntables "waterbed" floating in properly built NYC clubs and that really helping with vibration control. Maybe the heavy mass will be enough anyway, I've no shortage of that.
