I learned here and bought the Acos Lustre GST-1, so glad I did.
It has the smoothest VTA on the fly I have ever experienced, we don't really need OTF, except perfectionists, but it is quite nice when I change headshells, especially as it's my rear arm.
I'm lucky, I have two OEM headshells and they have azimuth adjustment. One, the screw is frozen, wish it was an allen head. I'm gonna have Steve or Ray at VAS change it to a new allen head that works. Maybe I'll have him change both now that I'm thinking about it.
