Mapman, in my observation, power cords especially on source has the highest impact on every aspect of sound compared to any other cables in the chain. I am not talking about entry level sources like the NAD, CA, Marantz stuff here. They do not carry signal but they affect the way the signal is generated, which is a more fundamental aspect than carrying a signal. I have had in the past many power cords, all of them being tried on my Reimyo DAC and the results were worlds apart from one cord to another...it was not splitting hairs, it was like even my mom in the other room could hear it. The tones went from being extremely bright to extremely dull with one change of power cord that too on just the DAC. There are many articles on the net on why a power cord makes so much of a difference, however I just go by my ears and always suggest the same to fellow audiophiles.
