An engineered floor can be problematic on a concrete slab. For my basement music room, my builder's supply store recommended against any type of wooden floor, even hardwood. Condensation issues, flooding issues, etc. Don't know if that could be a problem for you, but it's something to consider.
I eventually went with granite tile, which of course sounds bright. I mitigated this with a textured ceiling and irregular walls. And a large persian carpet. The room sounds lively but natural with ESL's.
