On the topic of power cords, I can't recall if we've had this discussion in this thread already, but I'm curious about others experience in terms of component hierarchy as it relates to power cords. Perhaps ideally, you would have the same power cord on all components, but this being the real world, where we upgrade cables one or two at a time you can end up with higher and lower performing power cords.
In that case, the normal question is, where to place my best performing power cord and so on down the line. I've read a few places and confirmed in my own system, that it was the power cord coming out of the wall, which then goes to the power conditioner or other distribution device that was most important and provided the biggest change in sound.
I experimented with this a while back but haven't re-visited this issue, so I'm not sure if my hierarchy would change.
1. Wall outlet to power conditioner/power distribution.
2. Source components (DAC, etc.).
3, Device power supplies (power cord to an LPS, that in turn powers something like an Uptone EtherRegen, or a Sonore UltraRendu, etc.).
4. Other source-related components (DDC's, USB cleaner type products).
5. Preamp (if used).
6. Power amp.
Curious if others have experimented and if so, what findings?
