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.

I have a two part OMA Plinth for my SP10 MK2, It has been great. `Previously had a wood plinth, made from butcher block. The OMA plinth made a huge difference in detail and soundstage layering. I currently have it on a Minus K platform, but only because my floors are wood and suspended, my house is wood frame and build in 1918.

I like that the tonearm mounting isn't cantilevered and simple to adjust.

It's highly effective and no compressor.

Hello,

I think all turntables benefit from isolation, I included it in my description only to give him fuller detail as to how I dealt with my plinth. When I heard the OMA plinth in their system before purchasing, they did not have it isolated in any way and it sounded terrific.

Of the three people using Minus K, none have parted with them and all have spoken as to enhanced detail, no negative attributes, but this is not a thread about Minus K.

I think a plinth which separates the motor/platter from the electronics should be ideal but cost more.

I did do away with the brake and the plastic housing, tightened the screws which hold the motor in place with a torque wrench to insure uniformityand the sound got better.
