Albert Porters after market panzerholz plinths

Franks,

There is a Boston mat that does not completely fill the recessed "cut" area on Technics platter but works wonderfully.

In other words there were two sizes available when Boston Audio and I spoke on the phone, I ordered the slightly smaller than standard diameter.

Lewm, the audiolife platter might add a small amount of drag at start up, but frankly it could just be my imagination since the deck has so much torque it really is not discernable. As for the servo, I wondered (worried) about that, but never experienced any issues - maybe the rotational mass cancels out all concerns! I also wondered if that extra weight might have a deleterious effect on the bearing. Also, I use a brass record weight that weighs a good 1.5Kg - even so the deck performs way better with the extra tonnage than without!

please email me if anyone want details on the acrylic record mats from Germany

RE: Diameter of Boston Audio mats

Just thought you guys all might like the following info I received this morning from Boston Audio:

"Both of these mats are 192.25mm in diameter. The size of the Mat 1 was reduced compared to the launch version about two years ago so that it would fit more tables (yours included I believe), and that was done before the Mat 2 was launched."

I currently own a TTweights Ultimat for my SP10 Mk II and am considering getting a Boston Audio Mat1 or Mat2 (haven't decided yet. recommendations?) for comparison purposes.

I agree with Albert.

We have a perfect, stock SP10 MK3 with EPA 100 arm and EPC 305MKII cartridge here at Oswaldsmill, as a reference unit. This has proved very useful in designing our own slate plinths. Anyone who would like to know how a SP10 MK3 in the original Obsidian base sounds (and I would imagine that Technics Panasonic spent a significant amount on testing and R&D of the Obsidian base) should come by for a listen.

Needless to say, I don't think there is any comparison even using an SP10 MK3 with a properly done high mass plinth (with a mere MK2.)
