What kind of power cord comes with expensive gear

It makes more sense for the expensive amp maker to include the cheap black one and NOT increase the cost of the amp then let the new owner spend whatever on whatever he wants IF they feel they make a difference.

Of the 2 camps:

The Believers will want to choose their own sound/flavor.

The Non-Believers will be glad they didn't have to pay extra for snake oil.

Win/Win.

Onemug is correct. Expensive gear just comes with a regular stock cord. A company's $30,000 amp will come with the same cord as their $3,000 amp. Their thought process is just as Onemug described.

I've talked to a couple of designers, and it's not that they feel that power cords do not matter, but they know that their customers are probably not going to use their stock cord anyway. Since they don't know what each individual consumer will prefer, they just leave that decision up to the end user.

At least they still throw a power cord in the box, they don't bother putting interconnects in the box anymore.

"If they come with run of the mill black rubber shielding cords i can convince myself to never buy an aftermarket power cable again."

Just think how much more $$$ will be in your retirement account! :>)
