TT Weights VPI center clamp


I was jus wondering, does the TT Weights VPI screw down clamp damage th record label in any way when it is tightened?

The original VPI clamps outer part does not move when tightened. only the center screw part moves so the label is not damaged. Other after market clamps for VPI seem to also use this method, and for the same reason.

The TT Weights clamps look real nice, but I am worried about label damage when using them. Can anyone with real experience please chime in?

I'm going by memory here, but I think I can remember a long time back, one, or some VPI owners disliking the Rubber Spindle Washer (as Doug recently brings up in this thread) and substituted a Carbon Fiber Washer of the same-similar dimensions as the VPI Rubber Washer.

Claimed there was some very slight improvements in Sonics.
Doubtful I would hear them, but some might? In the stock configuration, the Rubber Washer of course goes between Record, and Platter, and not between Clamp, and Platter.

I would assume supply houses, perhaps like McMaster-Carr would carry such? Mark
Yes, it is a concern, and one reason I wouldn't want a TT Clamp for free no matter how pretty it looks. The other major reason is, is this manufacturer veered from the original VPI design, in that the underside of the TT Clamp bears no similarity to the VPI Clamp design.

Without the proper dish in the underside of the clamp, you can chuck your rubber spindle washer away, in hopes of the TT Clamps properly clamping-coupling the record to platter, which it cannot.

Why does so many think they have a better mousetrap than Harry W?

Maybe, when they'll make a Clamp that is two piece, adheres to Harry's proven design, and clears the inside of a stock HW-19 dust cover, by not being too tall in height, I "might" consider one. Otherwise, stick with the stock VPI clamp, and spend the money making improvements elsewhere. Mark
I had forgotten, that such a topic, like all other audio topics can have as many opinions as there are posters.

Should the moderators permit, this could probably be a thread that could numbers into the dozens of posts.

Most feel the benefit of a clamp to be resonance control. Even Harry W himself no doubt believed this was the sole benefit. But of course there are others.

I know many here work very hard to achieve proper set-up of Table-Arm-Cartridge, and we can talk about things like Overhang, Azimuth, Zenith Angle all day long.

To me, it doesn't make much logical sense after all this hard work, and now you're placing an LP that looks like a Taco, or becomes Taco'd after improper precise clamping of an LP to Platter. Not to mention th extra work a Stylus-Cantilever has to do following a warped LP, and the detriment to good sound because of it.

The beauty of a Screw Down Clamp with Tables that posess the VPIS design, is variance of Clamping Force is easily obtained. With a weight, there's no adjustablity. The screw Clamp can be just barely applied, or provide much more clamping force than any weight can apply.

If one seeks the additional Mass, then buy the heaviest weight available.

All VPI Platters have been specially designed to work hand in hand with a Clamp that adheres to VPI's Clamp Design.
The use of the Rubber Washer was cheap, but effective, and smart.

Why TT Weights chose to veer from the VPI Design, and not at least provide a comparably designed product is unknown to me? I'm sure they have the expertise to make a beautiful two-piece clamp with adherence to the VPI Design had they chosen to.

I know many will comment about the sonic improvements, or lack of, with different Clamp Designs. I'm as well concerned that the Clamp-weight does it's intended job, and prefer the limitless range of adjustability/clamping force that a screw type design has.

I feel it does little good to be looking at a gorgeous Clamp, yet the LP looks like a Frisbee while in play.
While the azimuth error variance may be small, I would assume it is still there.

I myself chose a custom machined Screw Type Clamp made by a local machinist, but it does precisely adhere to the VPI Design. Mark
