Technics SL-1700 feet

I have no experience (yet) with their products, but just ordered a set of the large feet for my JVC turntable.  I'll report back once I get them.  

The JVC turntable has springy feet and I have springy floors which adds up to a lot of sensitivity to footfalls.  I have the turntable sitting on hockey pucks at the moment, which are much better at managing vibration and sound better than with the stock feet.

If your table is on a solid surface something like the Isonoe feet might be better.

@mads1 I’m very happy with the feet. It’s hard to say how much difference they made because I did a couple of mods to my turntable at the same time, filling much of the inside of the plinth with plastic-clay and adding the feet. The feet that the turntable came with were very springy. The MNPCTECH Feet seem to provide much better isolation.

Before making those two mods I had some serious feedback/vibration issues and they all but went away after the mods.
