SP10mk2: OMA Graphite plinth vs.Dobbins plinth

"09-20-15: Chakster
Steve, what about version for "12 inch tonearms? "

For 11" and 12" tonearms, I would need to draw new plans to incorporate longer tonearms into this plan. As it is, I drew my plan specifically for the tonearm I had planned to use in my instance, a Graham 2.2. And with no thought to producing any more.

I can say, after using this plinth for more than a year, I am happy with the end result. compared to a massive Baltic Birch constrained layer plinth, this 'light-rigid' plinth does indeed have a quicker sense of pace about it. Transients happen with a quickness not heard from the more massive base I had tried just previous. Plus, I have excellent bass performance in this setup that I would not have thought previously possible out of that tonearm and the two cartridges I've used on it. Very articulate and detailed...with great pace and slamminess. Better than I thought it would be.

The Mule Plinth

Yes, Chakster, I'm getting the "Obsidian Inspired" plinth in satin black/medium oak veneer. I customized with adjustable black Delrin feet (from a UK mfr near Acoustand) that raise the plinth about 2cm higher than the sorbothane feet pictured on the Acoustand website. I'm trading off a bit of the sleek, "low rider" look with the stock feet for ease of leveling. Just had the SP10 painted in black automotive paint. We'll see if it all comes together well! Bill Thalmann is also adding the Krebs Upgrade and installing a new bearing thrust pad. Experts like Bill may not be doing comprehensive SP10 work in the coming years, so I opted to address electronics and motor/bearing in a single shop visit. My PSU is a Dave Cawley "Timestep", so I'm set there.

I've received my "Obsidian Inspired" plinth. I had Acoustand install "type 1 black delrin height adjustable feet" from Ebay UK seller "kridon-image". The plinth has the simple look I was after. The black delrin feet blend nicely. Both plinth and feet are very well-crafted. The black painted wood requires care to prevent scratches. The plinth is lighter than I expected, but will sit on a very heavy Myrtlewood platform. My SP10 is on its way to Applied Fidelity for updraded sapphire bearing installation, with servicing and Krebs upgrade just added by Bill Thallman.I may have the table back for Christmas and will report on how it sounds once it is put back together.

Next week i will get my rack for Luxman PD-444 powder coated, it's my own design, super heavy, can't wait to try it.

I have few more Technics SP-20 tutnables and looking at EMT metal rack here i wonder why not use similar custom made racks for my SP-20 or SP-10mk2 instead of traditional plinth? It's some sort of the "nude" style prefered by some a'gon members. But wooden pannel can be installed on top for the deck and for the tonearm. I think this industrial rack looks cool.  

Some more info about EMT 930 / 927 seismic base is here.   

Hi Chakster

the EMT metal rack looks awesome.   please post pics

I am using with my SP10 mk3 / Technics plinth with your MS cu-180 platter mat with Stillpoint V's threaded into the feet positions, on top of a granite platform isolated by compression springs.
