Cartridge setup experts: Azimuth critique
Please watch this to understand WHY we adjust the azimuth angle. Spoiler alert: it has nothing at all to do with the stylus/cantilever assembly.     
Anyone Still Using Zerodust
We are actively working with Mr. Ishibashi of Onzow to investigate these questions more deeply. Early experiments show very fresh units of Zerodust do not appear to leave any paraffin oil after application.   
33rpm vs 45rpm - which is better
@mijostyn  - that's cool! What is max magnification on it? Once I catch up from all my travels I will be redesigning the top and bottom plate of the WallyScope to offer more "overhang" and "cantilevering" as well (I couldn't resist using our parl... 
33rpm vs 45rpm - which is better
If you can find the same recording pressed in both 33 and 45 and engineered by the same recording engineer, I would get them both to use as a simple evaluation tool for zenith error. Sonic differences between the two speeds are certainly minimized... 
Kuzma 4 point 9” or 313VTA
A shot in the dark: I have both arms mounted to my lab table. I have NEVER listened to my lab table nor either of these arms as I only use the rig for cartridge analysis. If you live close enough to Sonoma County, CA feel free to come by for an ev... 
Is this stylus worn out?
The distortion caused by worn fine line contact edges causes linear distortion of a type that is not annoying, but works to decay the soundstage, imaging, detail, overall intelligibility and high frequency extension. The high frequency distortion ... 
A new way of adjusting anti skate!
Answers to Lewm and timeltel questions are HERE. Be SURE to download attachment at bottom of page. There is no centripetal force vector that consistently aims toward the spindle. It has been a long time since I read Kogen, but if he claimed the e... 
A new way of adjusting anti skate!
Hi ninetynine. Measuring anti-skating force using a multivariate test as it seems you may be doing with a test record and an analysis of the electrical signal is fraught with many problems. Like a mosquito at a nudist colony beach, I'm not even su... 
A new way of adjusting anti skate!
Hi lewm, Study the Effective Moment Arm in the download. Imagine how it would be drawn if the stylus were underhung at various radii. Your answers should be there! By the way, drop the idea of null points having a significant influence on skating... 
A new way of adjusting anti skate!
At the risk of death by fire, I venture into this conversation as you both have points that are correct and some that I would address differently.  There are many factors that cause skating force. Even a pivoted linear tonearm experiences skating...
