Turntable platforms

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. 

My TT (Takai Final Audio VTT-1) rests flat on a Critical Mass System shelve with AT-616 footers under the shelve.  The AT-616 footers also level the shelve and thus the TT.  My set up works very well and I highly recommend.

I use a minus K under my Esoteric CD player to great effect.  The minus K is VERY sensitive to weight distribution and MUCH care is required while setting it up. 

Best,

Let’s talk about the Minus K for a second. Great performance, under 1.0 Hz in all of almost all directions of motion. I read you can drop a penny on the top plate of the Minus K and it will go into slow undulation, rocking and rolling and moving up and down. That’s what isolation, very good isolation looks like, small forces put it into motion with ease. The best isolation is when there is the greatest ease of motion. That’s also why it’s critical to square away all power cords, etc. that might constrain the motion of iso system for any spring type iso stand.

Minus K is center of gravity sensitive.  If your component is heavier on one end, it cannot be rested/centered on top of the minus K platform.  To do so, you might have to use a ballast on the lighter side.  Also, the component cannot be slid while resting on the minus K, as this can damage the internals.  Either way, it is great.

 I use HRS platforms under the mono-blocks.

Good luck,
Jose
