How good is the Obsidian plinth of Technics SP10 ?


Recently I heard an SP10 MK2 playing music at a friend's place. It was mounted on the stock Obsidian plinth. It actually sounded very good. I wonder how good is the Obsidian plinth compared to:

1. Typical after market birch ply plinths ?

2. Custom designed plinth like the Panzerholz plinths made by Albert Porter ?

Any ideas ?

I don't have my plinth anymore, this is how it looks "naked" on very special AT616 Pneumatic Suspension Insulators, 4 footers designed to hold the weight up to 60kg and turntable can be leveled perfectly. I saw smaller model of AT footers under your plinth. 

@chakster , My are AT 636. As far as I know only Raul owns

the biggest kind. I am not sure if those are your AT616.

BTW 60 kg capacity weight is ''overkill'' for the SP10,mk2 with

Obsidian plinth.

Are yours for sell? If I ever get Lew's Kenwood I will be interested.

They are, i have 8 of them in mint condition. The best AT footers ever made, same as Raul's, 4 of them supports up to 60kg. They are not for sale yet, but when you will get your kendood from Lew we can talk about it, but i think he will never sell his kenwood :)  

Dear chakster, I begin to believe that either your dad or you belong

to the so called ''Putins friends''. Such expensive footers and than

twice. ''Lews Kenwood''  is a kind of speaking. This does not mean

his sample but this model in general.  i have just seen one on A'gon

market for $5000. But transport and import duty in Holland (33%)

are the problem. I have the perfect tonearm for the second arm

place on this Kenwood: ''the arm'' or ''better Breuer'' (aka Sumiko

800). All good sellers compare prices all over the world. So I hope

that some German who understand English  and own the Kenwood

has seen this Ad. on A'gon. I can then collect the precious in

Germany and hope to get credit for your footers thereafter (grin).

I will be happy to sell my Kendood to Nandric. But not the Kenwood. I had a copper platter made for the Kenwood on the premise that it would be a better EMI shield than the OEM stainless steel platter sheet or mat supplied by Kenwood. Maybe for that reason, the copper platter raises the performance level of the L07D by a considerable margin; it’s easy to hear. The L07D Owners group recommends installing some sort of EMI shield for best results, so I am guessing EMI is the crux of it. Also, I previously used an EMI shield of a different kind, with good results, but had been going without it for a year or two, because that shield became magnetized and nearly ruined an Orto MC2000. Big mistake to ditch the shield entirely. Copper looks fantastic on the L07D, too.

Ironically, I purchased the MC2000 from Nandric.
