I put in a dedicated line in with a PSAudio Power Port and it it did lower the noise floor.I believe a hospital grade outlet or "audiophile" outlet simply has a firmer grip on the plug and the dedicated line isn't broken up several times on it's way to my system in other outlets.It's a fact that electricity can leak out into dust and dirt from the bare wire ends in outlets,light switches,and light fixtures.Just makes sense to keep all connections from the breaker box onward clean and tight fitting.
As far as power conditioners,I never found one that didn't cause one or more problems so simple surge protection does it for now.Hope this helps with your decision.
