I have two systems of hold downs in my tables, one a screw on clamp on the TNT - I've avoided trying a periphery ring on that table as I believe it requires a change in platter and a $2,000 bill that probably isn't warranted by any benefit in sound. The existing set up is excellent and I'd be reluctant to give up the composite platter I have that significantly benefited the sound.
The other table, a Sota Cosmos, has vacuum hold down with a screw on clamp and it is also very effective at taming mildly warped records.
I'd be interested in doing an A/B comparison on the same table, fitted with a stock clamp with and without the ring. What have people that have done that observed - any benefit on non-warped records, or is it just useful for the odd warped one?
