What are the audio differences you hear with turntable Mats.

@atmasphere that’s the answer I was looking for. I have a 2 piece aluminum arm board now, I’m going to look for a billet aluminum arm board now.

Thank you!

@danmar123 If the arm board is made to be non-resonant and so is less resonant then the plinth, the two will not vibrate the same way (of course, ideally both should be inert). This will allow vibration in either to be more easily transduced.

@atmasphere what I've been reading is that Corion is a good choice, this is why I asked the question in the first place.

@danmar123 It might be, particularly if the entire plinth is Corion and there isn't a separate arm board. It would be even better if the whole thing were laminated to a substantial aluminum or steel sub-plate so the two dissimilar materials could rob energy from each other. The metal sub-plate would also give the Corian some stability, something it lacks on its own.

@atmasphere the plinth of the table is cast aluminum, so if the Corion tonearm base sits flat in the plinth, you think I would need a aluminum ring? Or do you think Billet would be better?
