While a nominally isolated or separate filter bank of a power line conditioner can help to mitigate switch-mode power supply noise from polluting the AC delivery to other gear within a system, radiated noise (airborne noise) can still be an issue regardless of effective AC noise filtering. If there were no other choice but to use a switch-mode power supply for an audio application, I would likely use a true isolation transformer for the purpose rather than ordinary AC power line filtering.

Okay,I think I can follow that,& I'll probably investigate changing from the switching power supply that is feeding the X1 coming out of the PSA PP.
As I'm not using the X1 at the same time that I'm listening to my Music System,it might be interesting to see if this might pull "double duty" for my Auraliti PK100 DFP.
My question is "Can I tell what my power requirements for the PK100 would be from the information printed on the power switching transformer it currently is using ?" (Mind you,this is not to say that I honestly can detect any type of "noise" coming from my playback on my Audio System,just a music signal that seems to go deeply back into source material being played; If this can be "improved upon" though I suppose I'll never leave my house)
The stock power supply should have both the voltage and current rating printed on it...
