Turntable platforms

Good morning .   I am looking for suggestions, opinions, and recommendations for a turntable platform for my Transrotor ZET 1?   I have been considering the Synergistic Research Tranquility base, HRS, and Symposium?   Maybe some others?   I would love to get some insight.   Thank you.

Undamped springs will ring. If the frequency's low enough it may not be a problem, but the ideal is to damp critically. 

I can't see any downside if damping is an option. It may be impractical to damp a pendulum. 

6 directions? Don't you mean 3?

How did you achieve 0.5hz vertical?

If you’re so smart why ask me?

I recently demoed my unsuspended, 70 lb turntable on an HRS S1 platform and really liked what it did.  Better clarity, bass extension and micro detail retrieval.  Just swapped it out for a vibraplane for similar good sonic result with a bonus of zero footfall transmission which makes me think it may be even more effective than the HRS shelf. System is on a suspended hardwood floor.

The Townshend Audio Seismic Pod is a spring inside a rubber sleeve, with a tiny hole that allows air to escape when the spring is compressed (somewhat reminiscent of a bellows). The spring provides isolation, the rubber sleeve and compressed air damping.

In one of his You Tube videos, Max Townshend demonstrates the difference between the bare spring from a Pod vs. the complete Pod. Easy to find on You Tube, just do a search for the company name.

That would certainly explain why my simple undamped springs sound better than Townshend Iso Pods. Any restraint of the micro motion of the springs, e.g., the rubber fabric or the force of air, interferes with the effectiveness of isolation. As I said damping degrades the sound.
