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.

@best-groove, My Obsidian plinth looks exactly the same as

the one on your reference ''Here''. However instead of marker

B3 my sample has ''SL-1000,mk 2''.

It is not clear what you own because your description is not

clear but from the context one can deduce that the color of

your sample is different than black? Why is the color of interest

to you?

@nandric I was simply curious to understand why the Technics made this obsidian plinth (the photos are of my plinth) gray with veins rather than black like all those produced and seen in the world.

Is this a special series? I have never been able to discover anything about my strange plinth for this I ask in forums that I attend if anyone can know the story.
Been working on the project for a friend who has purchased my Technis SP-10mkII with Micro Seiki CU-500 copper mat. He decided to go Obsidian way and i was looking for SH-10B3 plinth for him. Finally i got it and it looks better than i expected in my studio.

Not sure how we can find a dust cover, but he asked me to find one. Must be hard to find. The Obsidian base will be polished by a local guy next week. I think it will be even better than what we have now.

I’ve noticed that we have to make custom armboard, because the Victor UA-7045 tonearm must be mounted 7-12mm lower than the level of the stock armboard to make the arm wand parallel to the platter.

The stock footers will be removed and replaced by mi Audio-Technica AT-616 pneumatic insulators.
Not sure how we can find a dust cover, but he asked me to find one.

I found an original dust cover for H10B3 a year ago, but I paid it very, very dear.

At that price adding a few more euros I would have definitely found a complete SH10B3 base.

Is mat Saec? differences compared to the Micro CU 180 mat?

AT 616 I not have you ever seen these feet in my life, hold up more weight than AT 636 and are they better?
@best-groove 

The AT-616 is much bigger in diameter than the older AT-636.
The 616 supports up to 60kg! But the smaller AT-636 support only 36kg max. 

Actualy on those pictures you see the mega rare 2.7kg CU-500, not 1.8kg CU-180 mat. 

SAEC SS-300 is the mat i use along with Micro CU-180 right now on my two Luxman PD-444 turntables. Saec weight is 870g, but CU-180 weight is 1.8kg. Actually even 1.8kg is too much for my Luxman, so the SAEC is better if the torque of the turntable is not so high as on the Technics DD. 

Also the price for SAEC mats are much better/cheaper than for Micro Seiki mat. SAEC is a champ of the mats in my opinion, the typical price tag is under $400 (depends on condition), but the Micro CU-180 price tag is under $800 nowadays. The Micro has its luxury look (copper) and it must be scratch free and clean, the SAEC is just black.   

I've seen a technical test of the most popular mats in the old Japanese magazine from the 80's. The SAEC is closer to the Micro CU-500 than to CU-180. I think all 3 mats are oustanding! Some of them just too heavy for certain turntables. Technics can hande all 3 mats with ease, even the superheavy CU-500!
