How to A/B Test Power Cables & Interconnects?

Looking for some advice. Here is the situation:

  • I am building out a new system (dCS Bartok > Parasound JC 2 BP > Parasound JC 5 > Floorstanding Speakers)
  • Equipment is on-hand. I am in the process of re-wiring the A/C circuit with two matching, 10awg home-runs (one for power Amp, one for sources)
  • I have the opportunity to try some high-end power cables and interconnects
  • I will invest in the cables if there is a discernible difference. I am somewhat skeptical.
  • I am trying to come up with a test protocol to determine what these higher end cables do. Everyone advises that I do A/B testing will listening to music. Of course I will do this.


My question:

Is there some more objective way to A/B test power cords and interconnects? I prefer to do this by listening,...not using lab equipment. How can I A/B measure system "blackness" or noise level?


Any advice appreciated. Thanks in advance.

I was really hoping the first two responses to my question would be both impassioned and contradictory!  Thanks guys!

If one wants guaranteed impassioned and contradictory responses, all one has to do is to start another topic about cables!

Auditory memory is not long.  Still, best to play one cable/component for a while, to get thoroughly attuned to it, and then swop in B.  Be SURE that the last track you played with A is the first track you play with B. Best chance of putting your finger on what you hear different. Thereafter, let B settle a bit, and check your emotional responses.  Do you feel pretty much the same listening to both, or more involved with one over the other.

If the OP could have a second person switch cables so he isn't able to know what has been switched, might be a way to A/B.
