Wow, @highstream this is a very unfriendly respons to somebody contributing to a thread in which you invited people to respond. Just because you don’t like the response you tell them to move on. Why do you ask for opinions in the first place?
Instead of trying to convince yourself that you haven’t wasted your money on power cables being rather impolite to those who share an opinion you don’t like, Turn on the AC12 powered system and enjoy your investment. I am sure it sounds much better than most of the systems on this planed that are powered with stock / standard power cables supplied with the equipment.
Nobody said the AC12 are bad. But it is you, who asked for a comparison judgement from others. As with all things in life there is always something better. Developments move on especially in electronics technology:
