Turntable platforms

Conspicuously absent is the Townshend Audio Seismic Platform (or set of four Seismic Pods).

If you have a suitable mounting point such as a sturdy beam, hang it from the ceiling. 

The platform can be a thick, say 5cm plywood or butcher's block. Metal might also work.

This offers almost complete lateral isolation, and with a little tweak to the cables, vertical isolation. 

millercarbon says,

Symposium and others pretend to do isolation. Really impossible, ultimately all anything can do is control vibration. Damp, tune. No such thing as isolation.

>>>>Are you channeling Michael Green again? You don’t even know what isolation is, do you?  Remember what the Little Train that Could says, “I think I can, I think I can...” Toot, toot! 🚂 

If you want to go all out get a Herzan. Otherwise Stacore, Vibraplane and minusK do a very good job.

Not sure of budget and size requirements, I have the German company  Clearaudio MontBlanc which is no longer made, but it has been the last stand I will ever need for my Transrotor Apollon with three motors and two tonearms. The replacement looks nice and is available from several US retailers.

Also, another one is the Copulare audio racks or tonebasen as known in Germany. I have the Aural and Sial series for components and amps. An audio buddy of mine had the top turntable stand called the Mozart, it is nice, but too much avant-garde for my tastes. http://http//www.copulare.de/sial.html

Did you get your Zet in the US? Is the dealer stocked with parts for Transrotor such as belts and spindle oil? Good luck.
