What are the audio differences you hear with turntable Mats.

@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?

@danmar123 If that was my machine I'd have an arm board machined of solid aluminum, same thickness and alloy as the plinth.

@atmasphere I found one from Cartridge Clinic off of Feebay, but still searching. Thanks
