Sound room flooring advice needed

I'm planning a remodel of my family room, which is on a concrete slab, currently covered with 50-year-old linoleum. I'll be installing engineered hardwood flooring.

What installation method is better for sonics, glue-down or floating? My main audio system resides in this space, doing double-duty as a 2.0 home theater. I listen to vinyl 90% of the time, so I'm also a bit concerned that floating could introduce footfall issues.

Thanks for your thoughts.
