Cdchas the right test. I am able to turn the volume up 100% and hear nothing 3" from the speakers. Just for fun I tried plugging everything into a standard outlet with stock cords and at 50% volume I could hear a whooshing noise from my listening position.
As far as the scam of power cords and conditioners, I have come to believe there is a lot of products out there that do little to nothing. I have tried a great deal of power cords and conditioners, and it's the power cord business that I most suspect. I found very little of true improvement in the $50-$700 price range. Most of the more expensive cords I tried di indeed help.
I live in a very quite suburb and receive my power from a pole mounted transformer 50' from my house. I am the only user on that transformer, so if it's possible to get great power I've got it. Power cords, dedicated circuits, outlets and conditioners all help my system. As the system has improved and become more detailed, the need for clean power increases. Perhaps the people who hear nothing have larger issues to address first.
