Albert Porters after market panzerholz plinths


I would like to hear from anyone that has purchased a panzerholz plinth from Porter Audio or a panzerholz DIY project.
Reading through all that I could find on this subject it's obvious Mr. Porter did his home work on his design.
My question to those of you whom refurbished, replinth and rearmed some of these direct drives has it advanced analog playback for you?

What is the weight of a CU-180? The stock MK2 mat weighs a bit more than half a pound. I would not use a mat that weighs much more than 1.5 lbs. It is not the bearing I would worry about; it is the servo action. The servo and motor were designed together for a specific total mass of platter + mat. But this is REALLY off-topic.
Yes it is the Micro Seiki mat,what mats have you guys tried and liked with the sp10mkii?
I can definitely see where a copper or metal mat in general could liven things up assuming the table drive can handle the weight!
If the M-S mat weighs 4 lbs, consider that the platter + mat now weighs over 12 lbs. (If memory serves, the MK2 platter alone weighs about 8 lbs.) This represents a nearly 50% increase in mass over the stock platter + mat (8 to 9 lbs total). I'm just sayin'....
Maybe it's harmless; maybe not.
