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?

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.
Dan ed, even though the Wright Phono preamp has 65 db gain and is able to accomidate the cartridge, when i tried a previous LOMC cart, I got a tube rush problem. However i think I had the cartridge loaded wrong due to my misunderstanding of loading. this may have exacerbated the problem. Maybe i'll try it without the tranny and with the proper loading and see what it does. But the problem does seem to be fixed at the moment. Thanks
Remember, a LOT of moving coil cartridges suck in the tracking department. If you could get a hold of a Shure Era III, IV or V test record you could quantify your cartridge's trackability. They're a nice tool to have. Other test records have trackability tracks, but the Sures are the real obstacle courses.

Why don't youn try an excellent moving magnet, like the Stanton 881S, Pickering XSV3000 or any of the classics? They show up in eBay every now and then.

Also, the Goldring Eroica is a rather decent tracking MC.

Choices, choices...
