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.

While preferring not to contradict anyone on stuff I cannot refrain from saying, in my own opinion, that Sorbothane, while seeming to be a perfectly good damping material, is actually not. Now, someone might possibly find some place where Sorbothane improves the sound, but I have found in most situations it ruins the sound. Like many rubbery, gel-like, soft materials Sorbothane appears to allow energy to be stored even more than it would be with no damping.

Geoffkait, that's interesting point.
Anyway those sarbothane pads are cheap as cheeps and easy to remove.

The main question is still the actual plinth for SP10. Someone like Raul use his SP10 in "naked fashion" and swear it's better. I never tried as i don't have any kind of tonearm pod (and SP10 without plinth looks a bit ugly).

Some plinths are just plinth (teak wood of whatever), but some of them must be a "rocket science" of plinth like those from Dobbins or OMA (according to the price).

It would be nice to look on OMA and Dobbins plinth in user systems on pictures (if someone could share right here).

this is the one from OMA, but it's not the budged single layer version, it's actually double layers plinth (looks great): http://oswaldsmillaudio.com/technics

If you're bound to use Sorbithane just get some Sorbothane insoles, or better still, hemorrhoid cushions. At least that's what I've been told. ;-)

Well Geoffkait, if you experienced with hemorrhoid cushions you can start your own thread.

We're talking about plinth here, sorry

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.
