Power Cables


Is it necessary to use the same brand and model of power cables for the amp and pre-amp? Any thoughts about mixing and matching? I know it all comes down to how they sound, but would love to hear your inputs or tips to guide me in the selection.

elizabeth, please keep us posted how the Pangea PCs perform as they age. There were a number of reports from the field that in contrast with most other brand cords the Pangea cords tend to get "worse" as they age. I've been using a couple of their AC14SE MKIIs in my digital source components for a couple of years and can't hear a difference as they age. They seem to be very well made but a bit rigid for tight spaces.

"Oh, dear..." Indeed!
For sure, I never intended to start a filter capacitor power-reserve competition but alas, that might be what I have done? I am so ashamed...
* And not only that! I see that my speaker cables are ’backwards’ - the printing reads [left to right] from speaker to amplifier. Oh No! But, at least both channels have the same "fault"! ;-)
