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.

Unfortunately, your ultimate goal won't be met until you tried EVERY suggestion here and whatever article you read. Even then, it may be subtle and definitely subjective.

Scientifically proven fact and  anectdotal experience aren't going to determine what your ears like.

That said, years ago, I tried the ridiculously priced 4" Mapleshade slab/pads underneath my VPI. It does create a convincing,difficult to describe,something vs. nothing.  It also looks kinda cool since  I have a cheapie $150 Sanus stand supporting everything .

I also have the brass footers under the table. A set of the black footers would look sharp under the Prime. I read somewhere stuff like the Stillpoints do magic as well.

Some of us actually like to experiment. In the larger sense...if it weren't for experimentation, this hobby would not be anywhere near what it is today.

If you floor is on concrete and your equipment rack is sturdy just use the maple. Wood that thick is very dead and maple is very heavy, perfect.
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. Seismic activity? Are you kidding me? We have an earthquake every 5 minutes? You might as well worry about your grandmother driving through your listening room in a drag line.

@dmk_calgary, this coming week I am taking a 4’ x 8’ x 3/4" sheet of 13-ply Baltic Birch plywood to a cabinet maker and having him rip it into various-sized pieces (22 x 16, 18 x 15, and 16 x 12). I will then make platforms, some comprised of 1/2" granite, a middle layer of ASC WallDamp, and the Baltic Birch ply. Stiffer and harder than maple (for less "flexing"), and hopefully pretty non-resonant. I’m obviously not into "tuning", which I consider the "wrong" path to take.

AVC (Audiophile Vibration Control) offers real nice shelves constructed of two layers of 13-ply Appleply ("pretty" Baltic Birch) with outer layers of cork, but one shelf is priced as much as the cost of a 4’ x 8’ sheet of Baltic Birch plywood and the charge to rip it into pieces, four 18" x 18" granite floor tiles (I have a neighbor with a "wet" saw who offered to cut them to size for me), and the required ASC WallDamp!

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?
