Outer ring - who uses and what are your findings

I use it on my Clearaudio Innovation; the matching ring fits perfectly so no fiddling with a centering spider/etc. I’ve made it part of my routine and never go without; it’s worth it, never having to worry about edge warps again. This particular table's platter is so massive, that the added flywheel effect is negligible.

I think it enhances the sound subtly (nothing major on otherwise flat records), but my main reason for its use is to combat warps. I also have a SOTA Nova V for a 2nd table, and its vacuum hold down is also very effective!

If you have any problem, or even exertion sensation, in lifting a 3-4 lbs outer ring, you should hit the gym. 3 lbs is plenty to flatten anything that's going to get there. In the Clearaudio system, the ring plops right on, perfectly fitted and centered via a lexan lip on the platter. That's less annoying to me than screwing in a threaded clamp, or fiddling with a reflex clamp. Also the vertical bearing is a magnetic suspension with 0 friction or contact along that direction, so the ring weight cannot cause any wear.
