Albert Porters after market panzerholz plinths

I can definitely see where a copper or metal mat in general could liven things up assuming the table drive can handle the weight!

i like copper too.

On the MkIII, the Cu-180 mat isn't a problem. It's a bit iffy on the MkII, however. It's not about the total mass of the platter but rather its moment of inertia. The amount of correction the MkII servo system makes in case of speed variance is related to a fixed value for moment of inertia. The total moment of inertia with the Cu-180 added is almost twice the stock value, so speed correction will be inaccurate, though possibly not audible.

I've seen some carbon fibre mats that might have similar properties but lower mass for tables that might not handle a 4 lb copper mat. They are not cheap but less than copper also I see.

Lewm and John what you say makes sense to me I'll pass on using the micro and try something close to the weight of the original mat when I get to that stage
Mikelavigne interesting line up of arms and tables I take it one or two in your line up plays large scale music better then other?

I use a SAEC SS300 metal mat on my Mk2 and Denon DP80. Weighs a bit over 1 lb and seems to be well tolerated in both cases.

Mike, I presume Steve Dobbins made your beautiful copper mats. (Well, he surely made the one on The Beat.) Does he sell them to the general public, or only to those who purchase a larger enchilada?
