RB 900 tweaking


What do members recommend about improving RB900 tonearms? I'm especially interested in the disabling of the spring tracking force adjustment, and not sure how that is to be done. I've read and tried the Origin Live recommendations, but wasn't sure it did what it was supposed to when I adjusted the force with my Shure force gauge. And what about antiskate when using this method? Thanks

Twl's comments are "on target", and I agree with them. The only point I'd emphasize is that you should consider the addition of the Expressimo Audio Heavyweight counterweight as MANDATORY, not optional. I have rarely been impressed by "tweaks", but I was absolutely astounded by the improvement that this counterweight made to my RB-900. The Heavyweight is the best "tweak" I've ever added to my system.

As far as I know, there is no after-market VTA collar that will work with the RB-900, due to the arm's mounting base. (The VTA collars that I've seen fit only the RB-300 and RB-600.) You can, however, use spacers (Rega supplies stainless steel washers) to raise the base of the tonearm. I found that my RB-900 (recently replaced with the RB-1000) sounded better with the rear of the tonearm about 1 mm lower than the headshell end, but that may be somewhat dependent on the cartridge you use.
David, the Rega, and the OL arms(at least the Silver that I have) have microphonic finger-lifts. I have shrunk about a 1/2" length of heat-shrink tubing onto the finger-lift of my OL Silver.

This is a known tweak for years on the Rega arms.
Tom, I understood that you were speaking about Rega-based arms regarding the microphonic lift. My question is whether you, or others, find this an issue with other arms, or if it is a peculiarity to Rega arms.
David, I don't know of any other generalities regarding this. I'd go on a case-by-case basis. I think that the long unsupported thin piece that is usually the shape of a finger-lift is likely to be exciteable by resonance in many cases.
I no longer have the stock fingerlift for the RB 900 it was replaced with a fingerlift from a Naim Aro arm and I think it is much better.

The HiFi mod is worth the money too. I would not want to be without it. The improvement was obvious!
