Again with the "expensive"?The trouble with many of the anecdotes where someone reports that an expensive power cord improved the sound is that there seems to have been a lack of curiosity as to why it made a difference.
The OP randomly grabbed a factory cord from around the house off something else.
I have stated issues with randomly grabbing cheap cords or the used equipment was bought with randomly selected cords as they got mixed up from what the factory originally had.
As to "Why", it was a crappy cord, most likely made of inferior metals, and parts.
So one needs to buy test equipment, learn how to use it instead of buying a better cord, one made of copper, shielded and with good contact points?If there was a buzzing noise with one cord, and no buzzing with another, then there are some very obvious tests and measurements one could do to try to figure out what was going on.
Oh brother, can you please tell us what is expensive in your mind? I think as I stated hereThere is little reason to think that the buzzing problem can instrinsicaly only be solved by means of an expensive power cord.
you fall into this thought.Funny how this thread is not about expensive cords, except for the one that want to say there's nothing to gain sound wise by a cord.
So we should pay someone to rewire our house, test the home wiring, move to another locating? Instead of buying a better cord, one made of copper, shielded and with good contact points?It is much more likely that the buzzing is revealing some deficiency in how the amplifier is coping with being in a noisy RFI environment, or with interference coming in on the house mains wiring, or something like that.
So the problem is the amps, amps made by top manufacturers at least in my case. We should take this equipment in to have it serviced and modified to make it better at a great cost.That deficiency in the amplifier can very likely be fixed by installing a cheap filter at the mains input to the amplifier.
Instead of buying a better cord, one made of copper, shielded and with good contact points?
Hunting around for a power cable that happens, at great expense, to solve the problems caused by the particular deficiencies of a specific amplifier seems to be an inefficient, random and expensive process, and one that fails to get to grips, in any proper sense, with what was causing the problem in the first place
Out of you post I got the fact you seem to be blinded by an argument that isn't even part of this topic. You solutions is far more expensive than someone getting a better cord, by making it of better parts, or buying one that you know what it's made of.
We all don't have our systems in the same environment or build them with the same components or even the same quality. It is our job building the systems we want in our locations, learn how to install it and overcome idiosyncrasies of our specific equipment and space.
