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 for sharing info on AVC.  Looking at their webpage and the Isolation Blocks could be helpful under my rack feet. Pricing is reasonable.  Have you used their products before?

No t_e_p, I was led to AVC by an Audiogoner who showed their platforms in his Virtual System pics. I’m a fan of Baltic Birch, so what’s not to like? ;-) However, I have sent two emails to AVC, neither of which has elicited a response. Not a good sign.

This is just my opinion, but I think a Baltic Birch platform (or a sandwich of BB/granite/constrained-layer damping) with a set of Townshend Audio Seismic Pods (or Machina Dynamica Springs) underneath will outperform the Symposium Acoustics Segue ISO Platform, good as it is. The reason? The Segue ISO’s design is a shelf comprised of outer skins of a very thin sheet of stainless steel, with a layer of foam between them. On the bottom of the Platform are five springs, available in two weight versions. A pretty good design some may argue, but the thinness of the ss skins and the foam between them doers not align with my notion of what makes for a good turntable (or digital player) platform. As I said, just my opinion. The design of the springs looks good, but nowhere near as sophisticated as the Townshend Pods. Plus, the Pods are offered in far finer graduations of weight/mass capacity.

And of course none of the above is as good as a Minus-K or Herzan isolation platform. But then, they aren’t priced at over two grand!

If your floor is not on concrete a good suspended turntable would be preferable and nothing you can do is going to isolate the table from low frequency disturbances like footfalls.
I'm not sure why you make this claim but you are completely mistaken. Perhaps you use a lightweight table that suffers such problems, but your claim definitely doesn't apply to all turntables.

@bdp24 - thank you for your response/comments. I think I'll try something similar. Not sure yet, will need to think about it and see what's available locally.

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.
