Michell Gyro SE upgrade to Orbe clamp?

I just bought and installed a Michell Orbe clamp upgrade to my Gyro SE. The instructions do not mention which way the acrylic finishing ring should be installed. It appears to have a flat side and a convex side. It fits over the knurled platter locking nut either way. So... should the finishing ring be used with the flat side up or the convex side up? Perhaps... flat side up for thick records and convex side up for thin ones?

Nevermind... I emailed Artech (U.S. distributor) and was told it should go concave side up with thin records and removed altogether for thick (180+ gram) records. Thanks anyway. By the way, Artech emailed me back with a concise, thorough answer within a few hours... impressive service!

I'll let you know what I think of the upgrade once I've spent some time with it. Yeah, it was kind of pricey considering the physical pieces that you get! But, the new spindle was very easy to install using a bench vise and everything I've read about the Orbe clamp is that it is far superior to the standard lower budget Michell clamp. We'll see...

I like the clamp. It is easier to use than the stock Gyro SE clamp. I find, like others, that it sounds best with the record clamped lightly, so that it is just barely flattened on the platter (i.e. not "he-man" tight). I am generally satisfied with the Gyro after this upgrade, but I am simply curious as to what will take me to the next level with my vinyl source. Will it be a whole new turntable, or a new tonearm, or a new cartridge, or what? I have a new high quality phono stage (Modwright), so that is not an option I am considering.
