Where to put your best power cable?

If you had power cables of varying quality that were large guage and the amplifier was plugged directly into the wall socket and components into the power distributor, would you put  the best one on the source, amplifier or the power distribution unit? 


I would try it both ways and let your ears decide. No way without listening is anyone here going to know. Probably best keeping your amp plugged directly to the wall and not your power distributor. Depending on what you PD is, you might try your other components direct to the wall as well. If you have say a PS Audio Power Plant then I would suggest the amp first, but even a PS Audio unit benefits with a quality cord. Fact is power cords do make a difference if your system is revealing or to that level.
