TT on Symposium Super Segue - slate or maple underneath?

I've gotten a Super Segue for my VPI Avenger. I have various things on hand I can place under the Symposium. I wasn't sure if a 3" thick maple block would work better than a 1/2" thick piece of slate. The whole thing will be sitting on top of my wooden equipment rack. I know ideally I should try both to see what sounds better, but hauling a 70+ pound TT on and off shelves for listening tests (not to mention moving a 3" thick maple block around) can be a bit of a pain. I'm hoping someone here has had some experience with what they've felt works best under a Segue, so I could try that first.

Thanks t_e_p. Unfortunately I don't have a Foundation rack, and the Segue will not fit comfortably on top of my old CWD rack (yes, I'll be moving to a better rack someday). I called Peter at Symposium and he suggested going Segue / slate / maple, but then I've been advised by others to skip the slate and go right to the wood. But I'm not sure what to do.

Thanks @bdp24.

@lak , do you think even if slate is used as part of a constrained layer solution? I've

the component on the iso stand should be placed on very hard cones AND the stand or anything under the stand should also be placed on very hard cones.


@geoffkait, yes I can see that as being a logical approach. But the Symposium concept, if I understand it correctly, is to dissipate the energy transmitted from the TT / motor into the Symposium material solution,  mitigating the need to use hard cone materials to act as a direct drain for the vibrational energy into the contacted surface. It seems like a one vs the other approach - dissipation vs. directed coupling. If (IF) the couplers and pods act successfully to dissipate the energy from the TT before it hits a lower platform, I'm wondering now if that would be enough? I reread Shannon Dickson's Stereophile article (I had forgotten about it - thanks bdp24). His case seems to recommend pure isolation between the device and the lower supporting platform, through the use of a Vibraplane or similar. I know the bottom line is experimentation will be in order - I guess I was hoping to trim some options off the list to maybe make it easier.

But after years of being here, I'll admit Shannon and guys like you here with your background probably know a lot more about this stuff than me. :-)

Is thermal dissipation the same as storage?

Where's a good place to buy ASC WallDamp?

It's funny to see the resurgence of Baltic Birch. Dick Shahinian, bless his memory, knew how good such material can be for building speakers. Although IIRC he used Finland Birch, back in the days when I think the stuff actually came from Finland. I agree it's great stuff.

Well, I decided my first experiment will be (and is) the TT feet in Supercouplers, which are resting on Super Point Pods, which are sitting on a 3” Maple platform, which itself is sitting on a 13 layer Baltic Birch ply platform. I’m listening to this for a while before I decide if I want to try ASC Walldamp between the Maple and BBirch. So far I like what I’m hearing.
