Hey DTX!
That's the crux of the matter. Unless you have an oscilloscope with spectrum analyzer and/or distortion meter most of us can't.
The Furman is VERY good at removing noise in the audible and EMI/RFI spectrum, not to mention among the best surge protectors money can buy.
My experience using the Furman has been long term. That is, if I don't use I feel I am not enjoying the music well enough.
So far I'm not a big believer in power cords, especially given their prices. I do recommend shielded cords as routine, especially when cheap or DIY'd as a profilactic.
