What is distortion due to?

Sounds like mistracking to me and has nothing to do with anti-skating. Increase the VTF (with AS dissabled)and note if distortion reduces. Upgrading the arm isn't going to solve mistracking problems.

OK, I can verify that it is only the right channel that distorts. I checked and did not have a twist in the wire. I increased my VTF to 2.2g, using a digital guage placed on top of the platter. Still the buzz was there. I then put a single counterclockwise twist in the tonearm wire and no help. I then tried screwing with the azimuth, rechecking the VTF after each adjustment. Then I undid the twist and tried different azimuth settings. I tried two twists and it was really bad! It got worse, then better, but never fully gone. Could I have a bad stylus? Was I right in checking and trying different azimuth adjustments? I have checked the routine alignment and overhang with the jig given by VPI. As far as my 51 year old eyes can see, its OK.

Is it possible the cantilever is tilted. It always seemed tilted toward the spindle just a little when I looked at it, so I had originally adjusted the azimuth to try to get the stylus/cantilever perpendicular to the groove, again by eye. I am new to analog so I don't have the experience to know what to listen for. But the channels seemed balanced and frankly I love the sound on most discs. Its just the distortion on some things that is killing it. HELP.

Should I get and try a new cart? I need my analog, cause it beats the hell out of CDs.

Trying different azimuths was worth doing. I've never had a cartridge so badly off-azimuth that it mistracked, but I suppose there's a first time for everything.

1. Are your records cleaned?

2. Is your stylus properly cleaned after every side?

If the answer to both is "yes", try reversing the cartridge clips and playing a few suspect passages.

If the noise switches to the L channel then the fault lies with your cartridge or its setup. The JMW's hokey antiskate "adjustment" would be a prime suspect, as would the stiffness of a new cartridge not yet broken in.

If the noise stays in the R channel then it's something later than the cartridge.

Dolifant, when you say:
" I checked and did not have a twist in the wire. I increased my VTF to 2.2g, using a digital guage placed on top of the platter"
- do you mean you placed the cartridge directly onto the digital scale?

If so, the indication on the digital scale may be reading 'high' by a significant amount due to magnetic attraction to the scale parts. My own pocket digital scale would read about 0.3-0.4g higher than the actual VTF if the cartridge was placed directly on the weighing tray. Those MC magnets are quite powerful.

The best option is to build a small ladder adapter (Wally Malewicz's idea) that distances the cartridge from the scale and also allows measurement adjustment to record height.

You post is very interesting. I too have a VPI Scoutmaster with Dynavector 20xL feeding into a Musical Fidelity A308. It's a great phonostage for being inboard, don't you think?

I had the same problem, a light crackling echoing high soprano voice and some high staccato piano passages. I tapped in the counterweight about a millimeter, (my audio guy set my TT up and I don't kwow where he set the tracking force, I hope it's not too much now, I'm waiting for him to call back), and it removed the problem, except for a very few passages of which I have since tested on multiple pressings. Same problem, whether London/Decca/SXL.

One of the worst offenders was Solti's Strauss Der Rosenkavalier in the final Rose trio; luckily it's not a problem on the Karajan EMI. I find it interesting that the VPI tracks 99% of other, sometimes insanely demanding high vocal and/or piano passages without any problem at all, why is that? Some pressing simply may be incompatible with some turntable combos. Luckily for us, as you seem to like Classical, we get to choose from many performances and pressing of the same thing.
