Testing the audible differences in mains cables.

[YNWaN]

Sorry John, not sure I understand, do you mean you tried to set up a blind test and involve a particular individual? If so, I can't say I am surprised - forum memberships are similar to the regulars in the pub - there's always someone who's done that, seen that, knows the brother of the best friend of the bloke who did it first etc - dig a bit deeper and it's often just hot air. Also, most members are more at home with armchair theorising than actually putting any of their ideas to the test!

That's why I offered to make some CD mats for people to try. I thought Marco and Co. would be prepared to give it a go and they are easy enough to make - better than just randomly hypothesising.

yes after that I gave up on this kind of stuff

I would happily volunteer to be the listener testee but I am not able to travel any sort of distance due to cost I'm afraid.

FWIW (probably not a lot as it's a single non-blinded observer with low sample size [n=2])
I recently changed the standard power cable on the Teddy Pardo PSU for my Wadia 170i/signature for a used off eBay Supra LoRad one and my ears told me there was a definite improvement (all be it small) in low frequency control & top and end clarity.
This was on the ring that does not have balanced mains. I should say that all the other equipment power cables in use are the standard "kettle" as I've given this area scant thought before.
