Technics SL-1700 feet

That’s for SL-1200mk2+ turntables. The SL-1700mk2 (and 1600mk2 and 1800mk2) have a proper spring suspension of the TNRC platform supporting the spindle and tonearm while the 1200 has a solid hunk of rubber. That’s also why the 1200 feet are better than the others. Add the 1200 feet to the spring suspension and you have as close to perfect isolation as you can get.

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.

The table is the original SL-1700 but it does have the spring platform.

@john421 just add ISONOE and you will be fine, for higher budget buy AT616 Pneumatic Insulators (very rare) as they can support much higher weight up to 130lbs (can be used under any turntable, including superheavy ones if you will ever upgrade your SL1700)

The spring suspension on the SL-1700 is excellent. The mounting should be to the plinth via aluminum brackets if it’s like the SL-1700mk2 which then suspends the TNRC floating base that carries the spindle and tonearm. Since the spring suspension is already giving you plenty of isolation, you don’t have to spend a fortune on feet.
