Kuzma 4 Point owners - Do you use damping?

Hi folks,
I have a Lyra Delos mounted on a 4 Point on a Satbi Reference.

I find my left speaker woofer bouncing quite a bit more than the right speaker woofer (on the majority of flat LPs, not warped) due to subsonics, but the soundstage is well spread and vocals centered. Not that I can hear anything from the subsonics, but I find it unnerving looking at it. And I have no "subsonic-off" switch on my equipment.

I think my cartridge is mounted "precisely" as far as I could, but I have no test tool to check for Azimuth or anti-skate.

I cam curious if anyone uses the damping trough on the 4 Point arm. Will damping help?

All other advice are welcomed too.
Thank you.

PS: I used to be a Rega user, so it's fascinating that I have so many parameters to play with...

Thanks, everyone for chipping in.

Areas to investigate:
1) alignment issue
2) rack placement

Alright, let me try them out and I will report again.
A friend is going to lend me his fozgometer. So let me check the azimuth and anti-skate first.

Cheers.

Just an update.
I have used the Fozgometer with the Analogue Productions Ultimate Test Record. Both channels' needle pointed dead on at "20" on the meter, although my Lyra Delos channel separation specs 30dB at 1kHz.

The best reading I got was "20" after tweaking the azimuth a bit; clockwise and anti-clockwise.

I have read somewhere (but forgot which thread) that the aim of the fozgometer is to get both channels equal and not for matching the channel separation specs ("20" vs 30dB). Am I correct?

Thanks.

Yes, you are correct about the Foz. The idea is to get both channels to read the same, or as close as possible.

As the Foz manual states, the actual values on the meter don't matter, just that they are matched.

Thank you guys for the confirmation on the fozgometer.

Next, i will play with the damping and report back again.
