I find that EMI/RFI noise adds a false brightness to the signal which obscures detail. I use a wide range of solutions to address it across multiple systems: dedicated AC lines, shielded aftermarket AC cords, power conditioners (for source components), shielded interconnects and linear or battery power supplies. I use a HDPlex linear power supply to feed both my Motorola cable modem and Cisco router and music server runs through a Tripp Lite conditioner.RFI and EMI sounds like what? Can you pick it out from the program music?
It was quite easy to hear the difference upgrading the power supply for my previous Touch player from noisy SMPS to either a linear or battery supply. I avoided cheap switcher wall warts from the outset for my current microRendu and Raspberry PI players.
Unless of course it is well shielded.Placing an interconnect between components increases the likelihood of RFI and EMI which works against your argument and almost forces you to drink the cablers' Kool-Aid.
