Which Cardas or Kimber cables did you try Sherlock Holmes that did not make any difference? And on what?

My dear @Watson)
The tone of your post makes it look like you are invested in the idea of power cables, and I trust the manufacturers to make their power supplies robust enough not to require special power cables.
I have not tried either of those power cables on the Nagra front end gear, nor on the Audible Illusions Modulus preamp.
If I found one to try I would be open to that, but I am pretty happy with the sound.
And in reality there is no way that the power cord is going to make it sing. If I was going to piss away that kind of money, I would be more likely to just go for the Nagra battery pack and not run any power cord into the Nagra gear.
The power supply supplies 12V, so unless I can see some smoother 12V, I am not likely to be swayed by well crafted creative writing.
But I would be open to trying it if it were readily available.
I would be even more likely to try these things if they showed the power supply voltage being more stable with their special cable than without it. But without some evidence, it devolves into the world of prose.
