spring loaded platform non-suspended turntable

Hello

I have installed the Minus K, it works just as advertised, no feedback which
has allowed an enormous amount in detail and image solidity to be
retrieved.

The process is a little jarring at first, my turntable is so heavy I needed to
move
it in pieces, then reassemble, it's not weighted evenly so I need to use
ballast to get the weight distribution correctly set-up.

I must admit, it's weird having such a heavy object virtually floating, it
reminds me of the film Gravity, I push it and it just a bit and it moves, then
returns exactly where it was. On start-up, the TT turns as the torque sets it
in motion, and then returns to it's place.

I can jump up and down next to it and it is completely impervious.

I am using a Newport stand made for scientific experiments. The legs frame
are made from extruded aluminum, hollow but extremely rigid due to the
form and how it all attaches. I bought it at a wholesale company which
specializes in medical and scientific equipment re-sale after companies
change gear, kinda like us actually.

Will need to continue the evaluation process but for now, I think it works
very well, haven't found any downsides.

Congratulations Crubio. I'm sure you will realize the benefit of isolation. On another forum I saw a photograph of the Rockport Sirius III. Interestingly, it sits on a custom stand designed for Rockport manufactured by Newport or TMC for their scientific lab air isolation stands/platforms. The Rockport turntable has the air isolation pistons on top of the stand just below the turntable plinth as opposed to at the bottom under the stand where the isolation would be further away from the turntable and be required to carry a much heavier load.

This design should deal more effectively with airborne vibrations hitting the stand which are thus isolated from the turntable. If the whole stand were sitting on isolation, airborne vibrations hitting the stand would make their way into the turntable.

I'm glad to see we have some serious audiophiles here.
