periphery ring clamps worth money

Yes, TT Weights are a better value and more effective then the VPI's, if you have a VPI turntable. How do I know? Tried both, the TT was a clear winner. Now, if I could only afford an electron microscope platform under the rig, happiness would be in sight. The madness goes on.

Bought my VPI Classic 3 new without the ring in order to save a few bucks; and a year later bought a used VPI ring off Audiogon. IMHO it improves the sound of all lps, warped or not. And it makes the TT look darn sexy. Highly recommended.

It depends on the rig and the system as a whole. The more help your TT needs to sink vibations away from the record and/or the more resolving the system, the more difference you'll probably hear.

On my Teres 265/OL Silver, a ring made a sonic improvement on all records. In truth, flattening warped records was a side benefit. The greatest benefit came from the ring's ability to help the platter absorb and reduce vibrations from the stylus-groove interface. Using it produced a consistently lower sound floor... less mud, greater musical and sonic clarity.

Again, YMMV depending on circumstances.

Hi Joeyfed, Just perform a search on "ring" in the analog section. You will find plenty of discussion on the topic.
