What kind of power cord comes with expensive gear

You just hit the nail on the head...and that is all you need to power up that amp/pre that so many here just spent a small fortune on. If that expensive highend amp/pre needed an after market anaconda power cord to sound it's best? Then the designers of said gear never heard their design at it's best..does that make sense?

I second what the previous two members said, and add the following:

The best power cord for audiophile purposes will be the best conductor of low frequencies and the best impediment to high frequencies, without restricting dynamics. Stock power cables are not very good in either respect. Indeed, I don't know any stock power cord that features any sort of high frequency rejection or attenuation. High frequency attenuation is important simply because the high frequencies that travel along power cords into your gear are the most invasive of frequencies: they are perhaps the most limiting factor to system performance. So, even if expensive gear comes with a basic power cable, these other reasons exist—independently of whether expensive equipment comes with cheap power cords—to investigate the effectiveness of power cords.

Perhaps I'm mistaken, but audiophiles generally accept that the quality of our gear's power supply has a significant impact on the end result of what we hear. For that reason alone, a serious music listener ought investigate the significance of the power cord. After all, as Robert Harley says (and others I'm sure), "from the gear's perspective, the power cord is the first six feet, not the last" (paraphrased). That is just to say that, despite it being at the end of hundreds of miles of electrical wiring, to the gear in question, the power cable is the most important wiring of it all.

Powercords... hah hah hah
I agree manufacturers usually ship with a cheap cord.
I use Pangea powercords. cheap enough. but I can hear a difference swapping them around.
So that is fine by me.

+1 from me!

Compared to the much of the animal kingdom, human beings have pretty terrible hearing. We have poor powers of echolocation, especially for sounds that come from behind us, we can only hear a relatively narrow bandwith of 20Hz-20kHz, and we’re easily fooled by illusions.But perhaps the most convincing tricks are the ones we play on ourselves. Expectation is one of the most powerful forces in shaping our perception, and it’s the reason that the same wine tastes better if we’re told it costs $90 instead of $10. The same goes for our stereo systems if you show an audiophile an anaconda sized power cord and compare it visualy to an genric cord. Which one do u believe he/she will pick out as being the best sounding? This is why blind testing works best determining if changes made are viable.
