Quality Power Cord

I have tried following cables: Pangea AC-9mkII; AQ NRG-4;
Shunyata Venom 3 and all of them affected the sound (highs).
The best sound was with the tiny $1.00 stock power cable.
UNBELIEVABLE!

Uh, how was it that you paid $1 for a free stock cable, and why would you do such a thing?

I've tried with the Signal Cable but it didn't work.
Lost highs, actually the sound became muffled with the "brushed" highs.
Any suggestions.

Though I do not have any personal experience with the Signal PC, power cord, I do have experiences with PC cable burn in.

Was the Signal cable new? If so how many hours were on the PC before you decided you didn't like how the PC sounded? What type of load did you connect the PC to, to burn it in?

With a $500 budget, I'd suggest looking for a Vitus Andromeda power cable. Threat cable sounds smooth, natural, and yet resolving. I preferred the Andromeda pc to my previous Acoustic Revive Power Reference pc which itself is a good value cable. Also all Vitus Audio's top components are internally wired with Anromeda wire.
