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?

It could be your cables have become intermittent. This can be checked with a meter. L & R should read the same. You might also want to check capacitance to make sure it hasn't jumped.

The other possibility is just the suspension everyone's been talking about. If it's broken in and sounding less quick and open, then you probably have too much downforce now.

Reduce VTF as low as you can while still having low distortion in the left channel with no antiskate an the hifi news record. Then increase the AS again until the right clears up.

I like the hifi news record more than the analogue productions one, which seems to require an intermod distortion analyzer. Even a simple scope or computer based analyzer isn't enough for that one. It's more pro oriented.
