My opinion is that you can use whichever power cords you wish, except any that you shouldn't use regardless of brand. My system has a big mix of power cables which I think are appropriate for the equipment at hand. An example is that I like to use silver cables from my turntable, a smaller guage of copper for the CD player compared with heavier cables for the power amps. I am sure you get the picture. I think it works well. If I had money to burn I might consider a "loom" from one manufacturer but it would still be tailored to the gear it serves.
Different Power Cords in same system - ok or bad?
I currently have a Transparent Audio Reference PowerIsolator power conditioner and a Transparent Reference Powerlink going from the conditioner to the outlet wall (it came with the power conditioner). I will soon be replacing the stock cords on all my components incrementally that will plug into the conditioner and wondered if it is recommended to go with all Transparent Power Cords or can I go with a different company such as Nordost, Shunyata, or Audience? I didn't know how important it was to keep this matched to my power conditioner and its dedicated cable. In case it matters, I DON'T have Transparent Audio speaker cables and interconnects. This is my only Transparent product thus far in my system. Thanks for your input.
