To my ears,I don't hear any degradation musically or added noise whatsoever.
All my amps,components are connected with lessloss PCs(DFPC).
All PCs are plugged into a Torus(PUI)on dedicated lines.
I find the Torus is too good an upgrade as they give me more amperage that my amps want on music peaks,quite an upgrade to say the least.
Lessloss sells a power conditioner(Firewall,I think it's called).
I like what I hear very much and I know for me the Torus are keepers,Lessloss PCs and dedicated lines are keepers.
It all works for me,think I'll put my horse back in the barn
