I don't think bass excavator was joking, he runs on "faith";
check his signature.
That's the reason he "believes" the power cord makes a difference.
"Beliefs" are resistant to any antibiotics, and so the believers should be left alone.
P.S.:check on that power cord here:http://www.nordost.com/35/odin-supre...nce-power-cord
where it says: "...all because the power on which your system depends is cleaner and arriving quicker
WOW! the impossible has been achieved:the electricity in that power cord now travels faster than the speed of light;
which means that electricity arrives at destination (your component) before
it has entered your power cable.
We could say that, in a sense, the power cable is a light accelerator.
bass excavator, you say:"Lots of scientific data lately" but you don't give us any links to that research;
and also you say:"Science doesn't come into play here. Science will prove or disprove whatever it tries". So, which is right and which is wrong?
You also say:"Reasons for expensive powercord? definition, legibility, and transparency. Is it ok in that order?"
You should do another kind of test, this will help you to identify which cable is best: disconnect all your speakers except the sub,
and then play some bass heavy music. Listen closely at the definition, legibility, and transparency of the sound you hear;
then report back your findings to us. It should be quite easy to do as deep bass sounds are usually not very complex.
You also say: "I feel
it has credibility but you have to spend money".
Does what you write here and elsewhere mean you decide everything you do or buy on hunches?
