Ok, I just got off the phone with Pete Riggle who sells and designed the VTAF. Pete is a very generous guy who takes his time in explaining how the VTAF works and how it is installed. For the P9 he sells a version of the VTAF that will work with the three point mounting system of the RB1000 tone arm. With this version comes a brass piece on which the 3 point mounting system rests. (I saw a picture of it somewhere online about 3 weeks ago, but now I can't find it.) Now the regular VTAF for the RB250 increases the height of the tone arm a little less than a 1/4 of an inch. I believe Pete said .23 inches to be exact. Now, the VTAF version for the RB1000's 3 point mounting system increases the tone arm height another 1/8 of an inch on top of that, so the total arm height is increased almost 3/8 of an inch when using VTAF with the P9 or P7 arms. This is quite a bit of tone arm elevation, but Pete includes different size shims to put on the rear side of the cartridge to tilt the cartridge back to make up for the increased tone arm elevation. He says using the cartridge shim creates no negative effects on the sound and enables you to have the benefits in sound that the VTAF provides.
Has anyone out there used these cartridge shims with their Vtaf? Where there any negative results from doing this?
Thanks,
