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?

First, I would disconnect the anti-skating. I find the XV-1s and XV-1t perform better without it in the 5 tonearms used here.

Second, make sure your alignment is accurate. Dump the factory protractor and buy a Mint LP, Wally Tractor, Feickert, etc.

Third, assuming the cartridge has 50 hours of use, try lowering the VTF to the 2.05-2.12 gram range. The XV-1s sounds muddy above 2.15g IMO.

Good luck.
