turntable isolation feet

I use Herbie's tall Tenderfeet under my non-suspended TT. I've also used the ball/isocup combination. They only work if your platform is level.

You don't mention what turntable you have. I have a VPI, which was greatly helped with the addition of Bearpaws...Vermontaudio.com

I would save money to eventually buy Stillpoints Ultra SS feet. You only need 3.

A turntable is a complex system and any vibration can affect the sound. I also found that VPIs were improved by adding brass cones; I used a different brand but would expect to get a similar result from the Bearpaws. Any table will be affected by external vibrations whatever the drive mechanism but there are differences. A massive table like the Aries Extended worked very well on a very heavy Star Sound rack but the LP 12 works better on a very lightweight torlite stand.
