Rega spindle too short

The benfeit of the recess is the same regardless of the platter material. Snug record/platter mating is a very basic no brainer. It is a major factor in just about every aspect of the sound. Consequently, IMHO, clamping is major. I was just at Musical Surroundings listening to the $100k Clearaudio Statement table that uses a ring clamp as well as a center clamp. Even with this MASSIVE assault and its center clamp, the difference was not subtle when the ring clamp was added. Even with the Rega and it's felt mat the improvement was noticable when using the clamp from my Maplenoll as a record weight lending more transparancy, solidity and body.

the Achromat comes in 3mm and 5mm thickness. the 3mm mat setting on your IA platter may be the ticket. It provides the label relief w/o touching your platter. The 5mm may also work, but that would only leave 1/8" of spindle to center your LP.

I did do a google search on the achromat and like what I am learning about it. I am going to purchase the 3mm just to be safe. The way I figure it, I already have 5/8" of acrylic. I figure that all I really need is a label recess, so the 3mm should be good.
