SP10mk2: OMA Graphite plinth vs.Dobbins plinth

According to the price lists they are in one category, but anyone could comment on quality/performance? At the moment i use big Teak Wood plinth (just $750) custom made in Taiwan for my SP10mk2. Looking for upgrade in the future. I use my sp10mk2 with Reed "12 tonearm now. Doest the plinth actually makes a big difference in sound? My stand is well damped with glass, metal and sarbothane in between.

1) Oswald Mill Audio graphite slate plinth (single layer) $2750, double layer looks fantastic but cost $3500

2) Steve Dobbins famous custom plinth cost $2650 including three Stillpoints feet and automotive show quality paint in black or white. Design has changed many times, still hard to find any current plinth picture online.

I know there are Albert Porter's and Artisan Fidelity quality plinth available, but i don't like the design (i mean just how it looks) for SP10.

@dover

They are fragile/brittle and many have cracks/chips.

But what about sonic quality of the b3 and higher models ?



@nandric

So those ’’negative reviews ’’ are written because of those worthless

feet. I was lucky to find those AT 636 pneumatic footers but those

are not easy to get. However Raul owns the bigger kind and my

own the 636....

BTW your new metal racks are also part of your plinth. Deed

you use sand or lead plummet to fill in the tubes? I used the

so called ’’quartz sand’’ for my ’’Copulare’’ rack.


Yes, my racks designed to be filled with sand. My ex AT-636 went to Australia for another SL 1000 mk2 owner. But i have 8 x AT-616 pneumatic footers designed for much higher weight, this model is adjustable. Maybe i will put them under Luxmans to try. TT-101 also waiting for some sort of plinth. I agree that the plinth should not cost more than a turntable (at least for me).

Try Jim Campbell (ebay jec965). He built my birch-ply and 3" slate plinths. A lot less expensive than OMA. Check them out in my systems. (No affiliation)

I can do it locally but the question is:
the SH-10B3 with replaced footers surpass the custom plywood or not ?

The big difference between professional made Obsidian plinth

and amateurs made plinths are the dust cover which can be

positioned at whatever level and tonearm board which can be

easy fastened with 4 big screws . Those sell for 600 euro  each

while their construction and quality can't be matched by any

of those ''alternative'' plinths. For my Kuzma Stabi Reference I

need to use an simple plastic  sheet in order to protect the platter

from dust. The dust cover on my SL 1000,mk2 I need to be clean

each week. Without dust cover all this dust will be transferred  to

to your LP's.

@nandric if you don’t know try this replica of the technics arm board and metal frame: http://www.acoustand.co.uk/collections/tonearm-boards/products/technics-sp10-tonearm-board-insert-fo...

Dust covers are good to have, but my two dust covers for luxman pd444 have been crashed in transit, i don’t use dust covers, i collect dust.

Well, i’m more concerned about the sound quality if there are any benefits of obsidian material over the plywood.
