Stylus Rake Angle


I am trying to set up my new VPI 3D arm as close to perfection as I can. On the Analog Planet, Michael Fremer gives one opinion, however, a different opinion was voiced by Harry at VPI, and Peter at Soundmith. I've been discussing this with them....Fremer says that SRA should be adjusted even if the back end of the arm is WAY high up as needed, whereas Harry, and Peter said to start with the arm in a horizontal position and move it slightly up and down to find the sweet spot. Peter said that my cartridge (Benz LPS) and some others have an additional facet in the diamond so bringing the arm up in back would be exaggerating the proper SRA. When I wrote back to Fremer, he answered with an insistance that he was correct. Does anyone want to add to the confusion??

I got a tip from VDH and a very tweaky audio buddy of mine who was a principal in a speaker group with Linkwitz and set up Pacific Rim shows for Rowland.

As a consequence, I now never (even with two tables: an easily adjustable and measurable air bearing arm and a Triplanar) adjust for the MM or couple for various pressings. However, I was told to forget how weird it looks and really crank that baby up in the air/measurable and not subtle degrees off of horizontal (higher at the back). I was amazed. I lost nothing with the experiment and have to admit that if Mr. VDH gives me that advice for one of his high-dollar Black Beauty carts he made for me, joined by my friend with some of the best ears I've ever known in 36+ years in this hobby: I'll try it.

Try it. The worst that will happen is it will sound like hell and you lose nothing. Of course, lab measurements and instrument calibration and set up would be nice, so I ain't knocking that. Give it a shot and trust your ears.
