Power Cord for Accuphase Amplifier

"Please keep in mind, after you scratch contact surface, contact resistance could dramatically  increase, and then plugging “new fancy” cord will give you relief for few days.. then you need to try to “improve” sound again, by buying new PC :-) "

- maybe in micro circuits, chips and tiny components, but in IEC plugs & receptacles, I don't buy it ... 

It pays to experiment and you will find one that works for you as there have been many good suggestions mentioned here and lots info available online.

Just don't listen to: jasonborne71, megabite, mazian, 1971gto455ho, classicrockfan.

"The most likely reason they recommend staying with the supplied PC is liability. The system has been tested / certified with that PC, and no others."

- That is correct, when I was in the business, years ago I sold high end electronics and after market power cords where only being produced by a couple dozen providers. We had this exact conversation back then. The three electronic companies I represented all provided UL approved cords only. It had to say that on the cord for the companies protection.

"it will sound no different than a $1,000 one."

- Have you done the experiment?

"I readily admit that these designer power cords look beautiful, but don't sound any different than a standard power cord. That is a legitimate opinion and many audiophiles subscribe to it. "

- You are absolutely entitled to your opinion, however don't inject it into a thread that the OP just wants suggestions from others on a PC for a specific amplifier. He clearly doesn't share your view or your arrogant attitude. You made it clear that you tried aftermarket cords and didn't hear much of a difference. That sir, doesn't mean that others don't. Everyone hears differently and brains interpret differently. Neither side is right or wrong, it just is.

- Yep, just because it has better measurements doesn't mean it will sound best to all. 

"What can be more arrogant than to dismiss science in favor of pure subjectivity?"

- Audio is not a objective endeavor from a listening point of view, it has to be subjective because the hardware has too many variables when interacting with other components. You then have human hearing and brain function where no 2 people on the planet are the same. Science can't explain everything because it was created by humans.

"Accuphase strongly recommends that you use only the stock cord "

- That is because they are not going to recommend an aftermarket power cord because most are not UL approved and ones they provide are relativity inexpensive. They don’t want to be liable if there is an issue and keeps their costs down, not because it sounds better.
