New expensive power cord for amp and no change in sound?

@immatthewj extremely bright and fatiguing. I couldn’t tolerate normal volume for more than few songs. My system is smooth and non fatiguing and I can listen for hours. But not with the Alpha NR v2. I had two if these at some point, one on Pass XP-22 preamp and one on Pass XA-30.8 amp and the amp just turned unlistenable. I gave it a full 200hrs and sent it back to Music Direct. I used to own older Taipan and Python Alpha Helix cords and they were open sounding but never bright.
So like I said, not every upgrade brings positive results.

And…no placebo here. I’ve gone thru enough power cables, cheap and expensive , with both good and bad results to know these cables matter. Take it for what it’s worth. My experience. My ears.

Obviously synergy plays into the selection of the right power cord.  Any cheaper cables that you did like?

The price tag does not always reflect performance. If this is a major brand cord then more than half of the selling price can be dealer and distributor markup and the rest of the cord could be sourced from major manufacturers such as Belkin or Eaton (who make excellent stuff to begin with). Put it in a fancy package and it's sold as "audiophile". As with everything... there's no shame if you don't hear a difference.

Yep,
