Thanks for the info theaudiotweak. If it's black and slightly grainy or lumpy, then it's going to be the same stuff, perhaps with slightly different additives. Would you care to confirm? I'm very happy that this is finally getting out, but in my opinion it should be $60 not $600. Based on the tiny cost (and relative ease) of manufacture.
If it's not black and grainy, I would love to know more.
