Last lemming, glad to hear that your problem is cleaned up (pun - LOL). I have a similar rig: VPI Classic and DV 20X2 HO (back-up carty). Just a Q and and 2 "fyi's."
The Q is how did you adjust azimuth?
The fyi's are the Sound Smith Counter-Intuitive counter-weight thingy greatly simplifies the process of setting azimuth and VTF, and its cheap (about $65). You may want to consider buying it.
Also, Peter Ledermann of Sound Smith, a pretty well respected guy in the audio/cartridge/TT segment of our hobby, disagrees with VPI's advice on setting VTF and AS. In short, he told me that setting VTF on the low end of the recommended range is better as long as the carty is tracking ok.
He also thinks AS should be used, but I honestly don't know how to apply his advice and I don't have the patience to learn. So, I just put one of those little rubber donut ring thingys on the business end of the AS device.
I honestly can't say the sound is better, but I am hoping to get more life out of my stylus. When Peter did my last re-tip, he commented that the sylus wear pattern suggested that AS was off. I'll report back later when I do my next retip.
In the meantime, I recommend that you give Peter a call, if for no ther reason than to buy the Counter-Intuitive device. He's a great guy and is always happy to give advice.
FWIW. Cheers, BIF
