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.
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 .
