Shure Dynamic Stabilizer on/off experimentation

Hi: I was wondering whether anybody had done the work to properly compare the sound of a Shure Cartridge with the Dynamic Stabilizer a - used as designed by Shure, b - still on the cartridge but locked in the up position, c - removed from the cartridge. To be valid the comparison would have to re-optimize the tracking force and antiskating each time. Also if you can report what tonearm you used that would be helpful; if you have tracking or resonance problems that would invalidate the experiment. For a nice tonearm/cartridge matching graph please see http://www.analogue-classics.com/html/sme_3009___3012.html.

I'm using an SME 3009 Series III tonearm with a SOTA turntable with vacuum holddown. Since the tonearm has damping and the turntable should minimize warp, the stabilizer may do more harm than good in this setup. Before I spend a Saturday doing the experiments I thought I would survey the Audiogon community.

I'd be interested in hearing your experiences please. Thanks!

Dear Hifi: This is what I posted in other thread about:

+++++ " Btw, I don't use the damping brush on Shure or my Stanton cartridges,I prefer with out it. It seems to me that the very sensitive microphone that it is what is the cartridge take some " sound " from the damping brush due to the friction between it and the record. " +++++

Regards and enjoy the music.
Raul.

Hmm,

I can see the argument either way depending.

Its been years but I always used it when I had one mainly because it helped keep the stylus clean.

No harm trying it both with and without and see what sounds better.

All:

Thanks very much for your responses. It is clear from your experiences I should try for myself running with the stabilizer up. I have the Shure test record which includes tracks for measuring tonearm resonance and a meter which I can use to compare the results. I'll post them when I get a chance. Regards, hifigeezer

The cartridge is now installed in an SME 3009 Series 3 tonearm, very low mass with fluid damping and the Dynamic Stabilizer up (not in use). I used the Shure test record and could not observe any visible tonearm/cartridge resonance from 6 to 11 Hz. This suggests that the SME tone arm damping is sufficient. I'll post more when I have updates.
