VPI Aries 3 - Funk Firm 3mm Acromat

I have an early VPI Aries Extended (12" JMW Memorial Arm) with a version of the "super platter."  So far, all the mats I've tried have degraded sonic quality.  I will be testing a sample of the latest VPI mat this week to see how it performs.

I use the supplied screw clamp with the rubber washer around the spindle.  I screw the clamp just tight enough to mate the record to the platter surface (light tapping on the record surface sounds hollow into the record is mated to the platter, then it sounds solid.)  It is very effective.  I have control over the amount of clamping pressure using the screw clamp.  The weighted "clamp" provides no variable pressure.

That said, I have heard superior performance using the Stillpoints puck over the weighted options (on a VPI Classic 3).

@stringreen  - I'm interested in following up on your suggestion.  Where are Harry's comments you reference?  Can't seem to find them on the VPI site.  

@stringreen 

Thanks for the info.  Interesting observation.  Glad you provided your $0.20 worth.  

So to put the suggestion into context, I'm using an Aries Extended with a threaded spindle and depressed label area.  A rubber washer of about 1/16" or so on the base of the spindle in the label area.  I use a VPI screw-on stainless clamp.  Also have a delrin clamp.  The clamps are hollowed out such that only the edge of the clamp is in contact with the record.  Are you suggesting possibly placing the coins along the edge of the clamp?
