Dear Raul, If I did write that I prefer the DP80 over the TT101, it was a typographical error. Because the opposite is true, although I do like and admire the DP80 very much. (I did and do say that the DP80 is less colored than the two SP10 Mk2's that I have owned.) I think if you'll re-read my post, you'll find you misinterpreted my words; I prefer the TT101 to the DP80 by a smidgeon. This means very little to anyone else. It's only my personal opinion. I will say also that the TT101 plinth should be discarded in favor of a more modern and higher mass design, IMO. That makes a lot of difference to the performance in my experience. Halcro and Thuchan (and also I) have done this.
I think you were quoting me, when you wrote, "those 21 lbs and the build materials and as you said does not impedes resonances". But I think you got me wrong, again. I wrote that the material composition of the Mk3 platter makes it rather more immune than most to resonating at a single frequency, because of the CLD construction. I then went on to concede that anything will resonate if you whack it hard enough, which IMO is an irrelevant way to test platters. But the MK3 platter would tend to resonate in a broad band of low amplitude, again because of its composite construction. The bottom line is that compared to most other platters, the Mk3 platter is more dead. I can only hope that the SP10R platter is as dead. It's lighter in weight, according to specs I read. Don't get me wrong, however, I would love to own a 10R some day.
The MS platter may or may not be resonant, but those heavy platters are made of a single metal, which may make a difference.
