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.

**** If you don’t mind, what was the VPI HW19 MK4 with springs supported by?
What was under it please?****

rixthetrix, the table sat on either a maple shelf on a Target rack or a maple shelf on a Target wall rack/shelf. The table’s stock rubber feet had been replaced with BDR cones, same as those that replaced the stock spring suspension. A brief experiment with sorbothane pucks between table and shelf was...brief...no good. Both the stock spring suspension and the BDR cones were tried with the table on both the rack and the wall shelf. In both cases the BDR cones were much better and the differences between springs and cones were consistent with the table on either supporting surface.
Great stuff from noromance and others; precisely the kind of thing this forum is supposed to be about, in substance and in style. Thanks.

My sole experience with springs has been the removal of the spring suspension in my previously owned VPI HW19 MK4 (TNT6, currently). My reasoning for that experiment was the following:

Most of our turntables rest on some sort of “isolation“ platform or device(s) which in turn rests on a rack/cabinet or wall shelf. Due to issues we all know about, mostly issues of resonance/energy transfer, whatever the table sits on becomes, in effect, part of the turntable. In the case of the HW19, four large(ish) springs, one in each corner of the “box”, suspend the metal top plate to which are secured the bearing/platter and tone arm. To my way of thinking, fundamentally, the box (plinth) acts no differently and serves the same purpose as do most of the isolation platforms or devices that we typically place under our turntables.

In this situation the removal of the four springs and their substitution with four rigid upward pointing Tiptoes (and later, the even better BDR cones) yielded very significant improvements in clarity, refinement, bass extension and subjective sense of speed. By comparison, the stock spring suspension always resulted in a more diffuse sound which was very midrange centric with curtailed bass extension and a somewhat bloated lower mid/ upper bass range. Most obvious was a band of unnatural brightness in the upper midrange that completely disappeared when the springs were removed. As noromance experienced at first with the Nobsound devices: “reduced bass and somewhat thinner sound”. The differences were not subtle and the springs were abandoned.

I bring all this up not to dispute any of the findings of improvement by those using these devices nor to make any general claims about the use of springs or not; quite the contrary. Mine was just one experience with a very different type of spring device. However, when I think of how many HW19’s are out there and how often it is recommended that the springs be removed, it seems to me that trying these devices in place of the stock springs is a no brainer given their cost. If memory serves, the dimensions of these things are just about perfect for this application. I will be ordering some for use under my electronics.

Thanks, noromance!
