Hardwood floors in basement music room?


I currently have carpet over concrete, and I'm thinking about removing the carpet and installing engineered hardwood over a glued down underlayment, does anyone have any pro or cons on this. The underlayment I was going to use is a lumber liquidator product called Eco silent sound HD, they also have a cork underlayment .

I have an opinion based upon a friends experience and my own regarding wood floors. Rigid floors improve bass and clarity. My own floor, suspended on joists, was carpeted and I replaced that with 3/4" Hickory tongue and groove boards. The floor is of course much stiffer now. I added area rugs which I'm sure help reflections. In your case, going from carpeting to wood on concrete will not change the stiffness. The big change will be reflections. Maybe you could try laying out some cardboard over the carpeting to get some idea of the potential change
I dislike any highly reflective surfaces in my music room. Stay with the carpet.
Thanks so much for all the great advice, I guess what I'm confused and concerned about is that I always hear how carpet over concrete is not good for sound and the best way to go is to build a wood riser and install your hardwood on top of that or install a wood subfloor first, but this room is already completely finished and if I build a riser or subfloor I would have to cut all my doors at the bottom and because of a bulkhead I would have ceiling height issues. I assumed from reading if I install hardwood it could and would improve the sound.If I do install hardwood floors because it's below grade (no-water issues)I still need to glue down some sort of vapor barrier or underlayment material and then I'm thinking I should glue the tongue & groove hardwood to that, just to keep everything tight and solid. Please give me any thoughts you may have on this and thank you.
I'm no expert, but I would think carpet over thick pad over concrete would be ideal. Adding wood, especially if it's raised, could introduce quite a bit of unwanted vibrations.
Never hardwood, carpet gets you a level playing field to get the other acoustics right. Go with a very heavy padding. Get a carpet with a 'cut pile', not a 'loop'.
