Setting tonearm angle?

I recently lucked out and got a great deal on a VPI Scoutmaster 2 with JWM 9T arm and proceeded to set it up.
I had never owned a high end table like this so the set up was a bit new. My question concerns the VTA of the arm. I set it by measuring from the bottom surface of the arm to the record surface at several places along the arm to get the arm as close to level as possible.
Is that a logical thing to have done? Would the sound better if the angle was biased in one way or the other? (Dynavector DV-20X2 H cart being used) Thanks.

I bought mine from a photo website. It is a Gitzo Tripod bubble level replacement. Here is one

Yup, I do that added weight to compensate for the added weight of the bubble level when when using it for leveling.

I found a bubble level set on Ebay...a tiny one and a REALLY tiny one...cheap.

"Why would the azimuth change when you adjust the VTA? The two are set in two different planes. The SRA and overhang, sure, but not the azimuth. "

It depends on the arm design. If the bearings are at right angles to the arm tube then the cartridge will tilt as it is raised and lowered. The bearings should be at right angles to the plane of the cantilever movement.

For a unipivot, it depends on the way the weight is distributed, or if it has a device like the Graham.

Raul, all,

Regarding the status of my knowledge re cartridge set up, I have come a long way since re-intering the vinyl wars some 6-7 years ago. Much time and effort has been expended in expanding what I know about better set-up.

That includes a DIY restoration of my Garrard 401, including plinth and mounting the arm (Dynavector 501). What I am able to enjoy now is so much better than my previious rig, a VPI Scout Signature.

I have found there is much to learn with the vinyl format, and that is why I enjoy it so much. I have learned a lot. There is much more yet to learn, (I don't think it ever stops in this hobby), and I will attempt to see what can be gained by checking overhang with changes in VTA. One caveat here, is my old eyes, which makes fine adjustments difficult.

I intend to modify my home made overhang gauge, so it can be used with the cartridge-headshell mounted to the arm.

Even without trying to fine-tune every parameter when VTA adjustments are made, the sound is always enjoyable, and quite good, I think. perhaps a bit more attention to detail will yield even better results.

Thanks to all, enjoy,
Dan
