Sorry, Bomby, didn't mean to misconstrue your words.
--I believe turntable design has truly changed through the years. Yes, it's still a rotational platter, yet, the ways to make it spin are everchanging.
--To all you table rappers out there, stop it. It proves nothing. Plus, I'd hate to have you damage your cartridge.
--To all Gingko owners or diy-ers of balls, your product and method can be fine, but not always, not for every situation and product. There are many ways to isolate--cones, points, balls, tubes, sandboxes, air, wood cubes, etc. Many will do a great job of isolating, and of giving support. Not all will "sound" great in a given situation. You may isolate the hell out of your item, but what if it does something to the sound as well? something not good?
--My opening glib comment was just that, these things have been going on for years--years! But I would never be a buzzkill for someone who's taking the interest to try and improve their system. We all start somewhere. For a lot of us it was the 80's.
--Apologies to Bomby.
--I know it's fun to experiment, but why not just use a wallmount if you're trying to isolate something? If that can't do it then you are in serious need of a solution.
