I can't quite read the brand name of my record clamp and the name I think is there, Belex, doesn't google up, But the device is lightweight and easily twist clamps to the spindle by compressing a rubber disc within. Yeah, it doesn't do much for edge warps, and if the LP has assumed a cone shape it'll only flatten it out when the cone is facing downward. I also have to support the bottom of my Sota's platter with one hand as I clamp the clamp down. But yeah, as far as I'm concerned it cleans up fidelity all around. Better imaging. Better transients. Less distortion. Better bass.
