New expensive power cord for amp and no change in sound?

I assume we are talking about a solid state amp?

I could see a power cord making a significant difference only if the original was inadequate. I would spend money on interconnects and speaker cables first.

as far as water coming out of a garden hose to a nozzle, if all the plumbing in the house is ancient and gunked up, it will have a detrimental effect on the water pressure at the nozzle connected to the garden hose.

Of course. Electricity works differently from the water. Supplying the quality electric current to a audio gear isn’t same as dumping the water ASAP (or pressurizing the water to shoot farther). It is more ready for the demand situation. So, I wrote in my last post *Usually, the audio gear doesn’t use 100% of current." Alex/WTA

@roxy1927 The reason you can hear changes with power cords has to do with the AC line Voltage drop across the cord. More expensive cables tend to have less Voltage drop.

But how much this affects various bits of equipment is a different matter. Some equipment is sensitive to Voltage drop and other equipment is not. It also makes a difference how much power the equipment draws.

If your amp uses feedback (and the Pass Labs does) then its able to reject to a certain extent the effects of reduced AC line Voltage, despite a high power draw. So if the $500 cable wasn't a whole lot heavier than the stock power cord, you may have heard nothing at all until you reached a higher power level, which might be well above your normal listening habits.

As you may have surmised, not all power cords are the same.

@mihorn Your comment “In my experience, a last 5ft power cord is much more important than in-wall wiring. Like a garden water hose, the nozzle only sees what it’s connected. The audio equipment draws the current from a power cord which is a bigger reservoir than in-wall wiring.” defies all logic and physics.

You seriously think that your “high-end” 5 foot long power cord is a “reservoir” for energy/electrons/electricity?

As I wrote, my words are from my experience. Please let me know what logic & physics I am against. May be I can explain.

In fact, having an only natural sound system in the world, I did many unusual things to my system that others don’t. Is it defying logic & physics? Alex/WTA
