Break in for new DAC

@danmar123 to be fair, he's referring to RFI EMI emitting from around the device. The power conditioner can only filter what's going through it and passed to other connected devices. It also can't filter EMI from the bundle of cords behind the cabinet. Does minimizing RMI EMI make a difference? I don't know but if it does, it would probably be like using a good linear power supply over a loud SMPS.

Correct. When you separate components and remove eni contamination you normally get less smear and better clarity. 

less smear and better clarity. 

This will be the result of some vibration and resonance control as well.

Placing components on a proper rack improves the sound. It’s tough to realize you have an issue with sound quality when you have not compared it to the same system set up properly. Been there, done that.

as a simple test you can order this gadget from amazon

So what are you getting around a metal enclosure such as an integrated amp / AVR vs a plastic enclosure like a modem and router? The metal enclosure is supposed to provide 'some' shielding.
