Anyway, considering putting down wood flooring in a few rooms at mi
casa. Substrate is concrete and there is really no motivation to
add a 1 1/2" subfloor as that will cause uneveness to other flooring
already installed.

I have heard of using a 3/4" floating subfloor over concrete by
laminating two layers of 3/8" plywood. Has anyone tried this?
