Help with vinyl frustration?


I guess it is my turn for some frustration with set up. I've read posts about it, but haven't encountered it until now.
I bought a new ScoutMaster about 4-5 months ago. I installed a brand new Dynavector 20XL which is supposedly a good match. However I have never sensed the magic that I believe this TT is capable of providing. I have checked and rechecked all calibrations. I have been up and down the scale of VTF/VTA. The problem persists.
The problem is that on certain songs on certain albums the vocals and upper mids/mid bass have a slight distortion. This might happen on one song and the next song sounds fine. This began just about the time of break in for the cartridge, maybe 50-75 hrs. As I said, I have checked and rechecked. I can find nothing wrong. I get the feeling that it is a very minor thing. Then sometimes I wonder if it is the cart itself?
I only notice this on classic rock albums which is what I play the most. I haven't heard this on classical albums. Which causes me to ask, Am I seeing to deeply into a poorly recorded record? But if so, why only certain songs on the album? And always the same place; vocals? This doesn't seem like an acceptable answer. Certainly if it is I guess I shouldn't have sold my MMF-7. However the SM kills the 7 on classical.

Anyone with any suggestions?

Artemus, doesn't K and K have a 1:15 or 1:20 step-up? Might be your cheapest solution unless you can trade your 20XL in for a higher output cartridge. If it were me I'd try to keep the LO MC thing going since that's my preference.
NO, you're absolutely correct. I'm having more and more of these "senior moments" lately. So you may be able to just eliminate the step-up. Worth a shot.
