I was told that a certain rack can lower the noise floor 20%. For some reason I find this hard to believe. I currently have a Billy Bags rack and it seems to be a decent rack. Of course there are better but they cost 5 to 10 times the price. It seems you could do better by doing a component upgrade if you are going to spend that kind of money. Does anyone here have experience with audio racks? And if so can you actually hear a lower noise floor?
