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.

but the Micro CU-180 price tag is under $800 nowadays.

I saw the prices in vertiginous climb for the 180 year since a year ...are all crazy!!!!!

I can feel lucky that last year an audiophile friend sold me his unused CU 180 for € 300.

I think that in the current days there is nothing better wanting to buy a good mat at honest price look at the Tenuto of PureSound done gun metal at 370 euro new and sold by the same manufacturer on ebay.

thank you for information Audio Technica 616 feet, rare but with so much luck you could find.
I will try to look for them.
You are lucky, because ugly looking and scratched CU-180 goes on ebay for much higher prices nowadays. I sold my spare last year for $750 to another audiogon member, but it was MINT- condition, this is the picrure. It’s nearly impossible to find Micro Seiki CU-180 "as new" without scratches and dirt on it.

I paid neraly $1k myself for my CU-500 in mint condition, it was more than 5 years ago and i’ve never seen another for sale! Even 5 years ago the CU-180 was about $500 minimum.

I am not interested in replicas as i am not sure the gunmental of the 70’s is the same as that copper of today. Anyway, i prefer the original products.

Surely there is a chance to buy some nice products cheaper once in a year or so, but i’m talking about the average price tags, vintage things like that only goes up in the price in time. It’s a good investment @best-groove
My friend decided to make a custom armboard for his Obsidian Plinth. The reason is that the original armboard position is still too high for Victor UA-7045 tonearm to make the arwand parallel to the record surface. I don't know why Technics made it like that (it's very bad). The Drive is lowered down in the Obsidian Plinth and tonearm must be lowered down too, but it's not. For example the Victor US-7045 must be lowered down in the armboard for 7-12mm. Victor has VTA on the fly, but even at the lowest position it is not low enough. Here is the Victor UA-7045 on temporary armboard that will be replaced with a custom made armboard soon.

Wow your CU 180 is really like new, the asking price has been adjusted!!!

My instead was so opaque and full of stains
before


but after so much cleaning I brought it back as if it were new.

SH10B3 base and tonearm panels have been developed originally to create the correct synergy with  EPA 100 arm and SP 10 II; if you want to apply other arms you will need to work on the height of the tonearm panel to adapt everything.
I would keep in mind that the "CU" mats made by M-S are expensive not merely because of their association with M-S but also because they are made of copper, which is very expensive these days.  I recently had a copper platter sheet made for my Kenwood L07D by a very good machinist who is very reasonable in his charges; it ended up costing $700, more than $200 of which was the cost of the copper sheet that he started with. Well worth the expense; it replaces the stainless steel platter sheet that is standard on the L07D and seems to do a much better job of blocking EMI, even though SS is supposed to be a pretty good shielding material.  I too also use an SAEC SS300, which I bought from Raul years ago.  It's on my TT101 at the moment.  I am not sure what it is made of and would be curious to know, but it's not pure copper.
