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.

BTW, I bought a set of Connex from 
www.partsconnexion.com years ago. I didn’t like the acrylic, as there was some noise when the springs compressed. Nice to see the Nobsound out of aluminum.

This is why Harbeths and other BBC designs are superior--you don't have to worry about any of this s$!t.

Ignorance seems to be bliss indeed.... :)

Any speakers need to be isolated even Harbeth , any speakers/room need to be treat and acoustically controlled even with Harbeth speakers in the room,, and all house electrical grid produce noise floor which is too high even those containing Harbeth speakers....

Idolizing a brand name is not a solution to embeddings necessities.... :)

I find it interesting that anytime I interject my experience in a thread, it goes dead. Sorry @noromance .
Lets try to make things simple. Play something with a heavy bass line and put your hand on the speaker/subwoofer. Any vibration you feel is distortion. Ideally you should not feel a thing. If the floor resonates it will do so regardless if the speaker is spiked to it or floating above it on springs. In order to keep the speaker from transferring vibration to the floor the resonance frequency of the suspension would have to be below the lowest note the speakers are to reproduce which means below 20 Hz. Tap your speaker and they will bob for hours. Bring on the damping. Above that frequency the speaker is free to vibrate and add distortion.
Floors are very well fixed in all directions except up and down in the case of wood joist construction. The degree of stiffness varies so every floor has it's distinct resonance frequency. Speakers generally do not point up and down. This is a good reason to avoid down firing subwoofers. You are less likely to excite the floor's resonance frequency. In most cases you are going to be better off fixing the speaker to the floor even if you are not on slab. The best speakers are going to have a very stiff heavy enclosure.
