Outer ring - who uses and what are your findings

"melm233 posts07-13-2018 10:51amI also have a VPI with an older acrylic-lead platter that I wouldn’t change. So I opted for a 2.5 lb. 3rd party ring. It is a TTW ring; they’re out of business now, but there's still a reasonably priced vendor..
Would you name the aforementioned vendor please?"

Here ya go:

I have a hopped up VPI TNT Jr (flywheel motor, sds, super platter and ring) and was playing it w/o the ring for like 6 months as its a bit of a pain.  Last week, I did an A B just for giggles and realize I should not be playing it without the ring.  Really adds weight to the presentation, more bass slam, better resolution, quieter back ground and more vivid three dimensional presentation.

Uberwaltz,
I apologize , I had tried the ring a few years ago ,
Vinyl Nirvana was using them on their upgraded AR turntables ,
I looked at the web site after I posted and was surprised to see all the Thorens tables. Shortage of AR's ? 
But I suggest you keep checking the web site for a used Merrill Heirloom tables that they have once in a while .
Check out the AR & Thorens Gallery Mike Castellana's " Heirloom-ette "
or My ( Daves of Vinyl Nirvana ) Refurbished Merrill Heirloom in the AR Turntable Resources .
Contact them to see if ring clamps are still available .

Cannot see myself changing out my Nottingham Analog table anytime soon and have not seen or heard of anybody running an outer ring on one of them but who knows?
