I use a Vibraplane which is similar to a Minus K. I agree with Mijostyn and I wouldn't worry too much about this if your Minus K is setup correctly. However, like Whart, I also use an HRS (with their non-spring loaded feet) or Symposium Svelte platforms. This further improves the isolation in my experience and would reduce transmission of vibrations to the turntable. These platforms are also supposed to help "drain" the internal vibrations from the turntable. All I know is that I like the presentation a little better with the HRS or Symposium shelves between the table and the Vibraplane.
Minusk platform
The topic concerns mostly those who use a minusk turntable platform.
I am using a minusk under my turntable. The only issue i have is when i give an impact directly on the minusk (using my finger for example) OR on the platform on which the minusk stands, there is a metallic sound - ringing heard. This sound is also heard from the speakers (i use mc cartridge). Obviously the minusk being metal it will cause higher frequency ringing. This will be over 100 Hz where minusk runs out of isolation.
what way have you solved this issue or did not have to?
thanks
