Cartridge for VPI Classic 3?

I had the 20x2 low output on the classic 3. The XX2 Mk II was really worth the extra money when I upgraded. Based on my experience and in my opinion, I suggest if you are considering Dynavector go directly to the xx2 MkII on the Classic 3, it is really that much better. For me, getting the SRA at 91.5 degrees also really paid off in improving the sound.

I pretty much used the procedure by Michael Fremer on Analog Planet > Setup tips> How to use a USB Digital Microscope to set 92 degree Stylus Rack Angle (SRA). I used a different digital microscope (it was around $40) and is very high power, 800x. It is a little hard to use at that power, and I also needed to take off the front protective piece so I could get it close enough for the focus. I took the image, transferred it to Powerpoint, then drew my graphic lines on the image. Then I measured the angles with a protractor on the screen. I repeated the procedure, raising the VTA tower, until I achieved the desired angle, 91.5 degrees.

Every stylus is different, so my setup might not work for you. I needed to raise my VTA tower significantly to get to 91.5 degrees. What is nice, is it gets you in the ballpark and then you can fine tune by ear.

Also, make sure to check your MINTLP again, since as you raise the VTA, you will also change the geometry of the arm, and you will need to re-align on the MINTLP.
I am at 2 grams VTF and 100 ohms load right now, but still optimizing.
