Turntable Mats for Technics Grand Class, "G" Series

So I was just curious why you stipulate that the mat needs to be glued to the platter.

@lewm That is specifically in the case of the Oracle mat which is designed to be used in that manner. 

I have a mat at home that is the same kind that SOTA used on their early Cosmos turntables; it was sold as an item by itself prior to SOTA acquiring the rights to it. It does not have to be glued down.

Why does the mat have to be glued to the platter? Seems to me you’re better off with nothing between mat and platter, for best energy transfer.

@lewm It depends on the platter pad to some extent. But the pad, if its doing its job properly, is damping the platter as well as the LP.

To do that it must be the same hardness (durometer) as the LP, and then have damping properties so all the energy coming from the LP as its being played is absorbed with none reflected back.

@stereo5 @pryso  There are three screws that affix the platter to the motor. If you apply the mat with them in place you'd have to do surgery should you ever want to remove the platter for shipping. So those screws would have to be removed first.

The Oracle hard mat was recommended to me for my Technics SL1200G. I tried it but wasn’t really satisfied.

@stereo5 The Oracle needs to be bonded to the platter for it to do its job. You didn't do that since you were able to 'go back' (you would have had to chisel the Oracle off, since it has a pretty effective permanent sticky back) so you really didn't hear what this pad is about.
