Are some tracks impossible to track?


I had been having a problem with a few lps, that I thought were completely solved...distortion on highly modulated tracks in 1 channel due to not enough anti-skate. For the most part its gone.

But I just got a 45 rpm recording (Maria Muldaur...Richland Woman Blues) whose 1st track still distorts, a little on both channels. So I increased the VTF to 3 grams and got rid of the problem. BUT...the recommended VTF is 1.8-2.2 g. Am I screwing up my other 99% of lps by tracking at 3g. I do not notice any negative effects when I play other lps at 3g.

Now even at 3g, when I play Beethoven's Hammerklavier Sonata (Pollini/DG) there is still very slight distortion, when he "hammers" at the piano.

Rig: Scoutmaster/Sumiko Blackbird

So are some tracks simply untrackable or should a properly matched arm/cart, properly set up track anything? VPI swears the Blackbird is a good match for the JMW 9. I have triple checked everything re: setup, but I am new to analog.

The Shure V15Xmr (if you can still find one) tracks anything and is reasonably priced. Sounds good too.
Qdrone...Antiskating force is caused by drag of the stylus and the geometry of the arm. The drag varies with groove modulation, and is always more than what occurs with a blank disc. A test record with a heavily modulated pure tone (so that you can hear any mistracking) and an arm that allows you to vary VTF and antiskating force while playing is the best method. Actually, I long ago gave up on pivoting arms because of all the critical adjustments, and use a linear tracker.
Dougdeacon...Just to be fair, a blank disc is good for demonstrating that a significant skating force exists. It is no good for setting accurate antiskating compensation.
Qdrone...God has more important things to worry about than antiskating force.
