Springs under turntable

I picked up a set of springs for $35 on Amazon. I intended to use them under a preamp but one thing led to another and I tried them under the turntable. Now, this is no mean feat. It’s a Garrard 401 in a 60pound 50mm slate plinth. The spring device is interesting. It’s sold under the Nobsound brand and is made up of two 45mm wide solid billets of aluminum endcaps with recesses to fit up to seven small springs. It’s very well made. You can add or remove springs depending on the weight distribution. I had to do this with a level and it only took a few minutes. They look good. I did not fit them for floor isolation as I have concrete. I played a few tracks before fitting, and played the same tracks after fitting. Improvement in bass definition, speed, air, inner detail, more space around instruments, nicer timbre and color. Pleasant surprise for little money.

I am waiting for someone to advocate some sort of springs for one's listening seat.  After all, if all the equipment is bouncing around, shouldn't the listener be moving in tune?
Indranilson, I would not be too anal about perfect level for your turntable, although it should be very close to level if not perfectly so.  But what is more important, if you are going to spring load it, is that the spring action moves the table in the vertical direction with perfect symmetry or near to it.  You don't want an external disturbance to cause one end or corner of the table to move more than any other.  In the extreme case, this could provoke a mechanical oscillation. Could also cause problems with tracking the LP.

@lewm - I won't advocate for springs under the seat, with the speakers and electronics isolated correctly, there's absolutely no need. However nice padding to make it comfortable for hours of listening pleasure, ah yeah, I fully advocate for that!

Enjoy the tunes :-)

I don't use a sprung turntable, but in the days I had a Linn....the springs should be wound in different directions to cancel each other's bounce.

Yes Uberwaltz, you are right but the resonance frequency of the suspended units is so low. In Boston after the Big Dig a concrete paneled ceiling in one of the tunnels broke and collapsed on a car killing I think it was two people. Traffic though the tunnel created very low frequency rumble exciting the panels cracking them.
Again, they are so heavy there is not near enough energy produced by even the largest system to get the concrete "ringing"
That would apply to apartment buildings, office buildings and skyscrapers. Not to mention you can't play a system very loud in those buildings without pissing someone off.
Most of us I would assume (maybe I'm wrong) have reinforced concrete slabs sitting on compressed stone dust, a wonderful floor for a Media room.

I think you just described my room Mijo, lol.

And which is why despite the too large amounts of glass it still works pretty well for me as my music room.

I would still think there maybe some slight differences but not sure how  you would start to prove it.
