Dynavector XV-1s and JMW 10.5i question


I recently purchased a new Dyna XV-1s for my Aries 3 and JMW 10.5i. I had a buddy set it up and it initially sounded fantastic. Recently I have noticed less air and a slight shift of center image to the right. It's also a bit less involving.

I know he had set the tracking weight at 2.2 grams. The weird thing was he had to put a small dollop of blue tack on the end of the anti-skate rubber ring weights to give it more anti-skate based on test record distortion in the right channel. I'm a complete novice at this stuff so I am a bit lost, but from most threads I have heard that little to no anti-skate should be needed with JMW 10.5i. After discussion with my analogue buddy who et up the cart, he said maybe it needed more anti-skate and blue tack.

I have ordered an Analogue Productions test record for myself and the Fremer DVD. I can (and will) ask my turntable guru buddy to come back and look at things again, but I don't want to 'over-ask' for his help and I want to start to learn about this on my own. Can anyone offer suggestions to help me 'find the magic' again with more air and a better solid center image?

That Blu-Tak is silly. You can set the arm up using the supplied VPI protractor, however, I found that the MINT protractor provides more accuracy, therefore better sound. Use the mechanical anti=Skate device making sure that the little arm is horizontal at the beginning of the record, and raises during play until the end of the side. Play around with VTF..every cartridge off of the assembly line needs different VTF (within the manufacturers suggested range) to play the best. There is an allen keyed weight inside of the rear of the arm that you can fiddle with. Make the arm the heaviest, and gradually unscrew that weight which incrementally reduces the vtf, until the sound zeros in. Regarding damping...add only a drop at a time listening to its affect. It will get better, then one drop more and the sound is ruined. Use a Q-tip to remove that last bit of damping fluid.
