VPI acrylic vs. aluminum

One more point: in anything mechanical, in the case of this forum post, (turntable, tonearms, cartidges,) machining tolerances are extremely important in overall end musical satisfaction. Take some cartridge lines for instance, the only difference in some models are the closer tolerances that were found after the manufacturing/machining process was completed for a specific model, and only, after final testing of these parts, found to be much better sounding, therefore the manufacturer creates a new model that sounds better/costs the end user more (costs the manufacturer no more) from the batch of original cartridge parts for one specific model.

melm: With all due respect, I've read through this discussion a few times. Even though I've tried to explain my personal experiences with these differing platters/bearings, you have, (without as much personal experience, as you stated), have again & again asked questions that show that lack of experience or thoughtfull reasoning that should be considered here. The questions you've continued to ask, show this. It seems you have either an unwillingness to accept others' personal experience without careful thought or the fact that ongoing improvements in mechanical design/machining tolerances, just may be an improvement to your listening experience. For these reasons, I will not post here again.

I only hope the OP has gained some insight here.

I hope you all have a good day.

What is a mag/level platter?

Here's the platter: http://www.avsforum.com/forum/imagehosting/75530955554817eb537e.jpg

There is a gap between the top and bottom platters. A belt-drive motor spins the lower segment while magnets link the top and bottom.
