you've a perfect opportunity in front of you presently to find out with regard to the Akiea counter top materials.
I thought and planned, and thought and planned and tried several materials other than Maple for footers and platforms. When I CAD some Maple stands (solid Maple BTW) the price I got for somenoe else to glue them together and rough sand them though not fit them together... I'd do that... the price was incredible. Well over $500. for 2 inch thick end grain hardwood Maple. Nothing exotic actually.
I found the Ebony and Mahogany IMO superior were I to have gone that way. I didn't.
I had to buy squeaker stands for my HT rears, and had already bought a Sound Anchor six shelf damped rack, so I called SA and inquired about amp stands instead. that wound up being a great move and quite fortuitous. got a pair of damped amp stands for $250 that had been ordered by a amp maker that didn't follow thru with his order... I'm definitely pleased and all my stands and such match too.
If I had that counter top I'd rip it into the size I needed and play with the supports, Blue tact, spikes, adding a pocket underneath I could fill ... etc.
To go out and buy all the materials straight up, cut plane, rip, fit, glue, clamp, sand, sand, finish sand, stain, drill, spike, seal, and dampen, it might pay to think of other paths which may well prove out less expensive and be as good, or better ones.
