I'll probably look like an ass, but oh well:

when I had a Rega RB300 it was too low for my DL-110 I could not find the cash for a proper VTA adjuster, so I read the pro bicycle spacers for the headstock work well. I went to Performance Bicycle (a U.S. chain) and they had some for $3.99.

You get a set of 3 in white or black or carbon fiber (i think that is more). They are indestructable because they are made to withstand bike torquing and riding conditions, much more than any puny 12 gram tone-arm.

Well... they worked well. I only needed one. The caveat: you can only raise or lower by the height of the spacer, not incrementally like an expensive VTA adjuster. The guy who suggested also had a Rega RB-300.

Cheap way to see if it is needed or not.
