I never was aware of this issue at all. I just go out and get speakers and then get an amp powerful enough to push them. I plug the sources in and it works. I've never run into problems with it at all. I'm wondering if this is a real world problem, or if it is just more doubling down on stuff the might be important for a recording studio where you need as low of a noise floor as you can get, but really doesn't apply to home audio where noise floors aren't anywhere near audible in normal use.
