Give Brian Berdan at Audio Elements in Pasadena a call. He was trained in the art and science of turntable/arm/cartridge set-up by his pa, the legendary Brooks Berdan, and is now himself an expert.
Do you still have the cartridge alignment protractor supplied with the Helius Omega? It’s design incorporates a unique offset bearing design which renders a standard protractor unsuitable for the arm. If not, see if you can acquire one from the U.S.A. Helius distributor, Dan Meinwald at Sound Advice in Long Beach.
Great table, great arm!
