Calling that insulting? Wow. Trying to sell people cables that "offer much better SQ, increased detail"etc etc, that is *insulting*!
So you've listened for yourself and not heard a difference? This is the Sound
Science forum; can you provide ANY sort of backup for your claims that power cables can and will never affect sound quality?
depends. if I start turning my power cable into a massive low pass filter, is it still something we should call a cable?
it's not difficult to make a cable that will change the sound, we simply have to make it so that it's not the cable it's supposed to be. as in, a wire with minimal impact on the signal passing through it. that's what a good cable is supposed to do right? if to you guys a good power cable is a good filter, we're simply not talking about the same thing.
and why should it be the job of the power cable to filter out noise? doesn't it seem strange even as a concept? the amp manufacturer ran out of space inside the box so he couldn't fit the oh so needed filter? am I supposed to go with that kind of story? the simple concept that a power cable should do something special is strange to me.
you have yourself heard such differences from power cables, let's pretend they were real(something you haven't showed to us so far), you don't know the electrical characteristics of the 2 cables, only that they don't sound the same at some place on some device. so you can't even rule out that one cable could be bad. or that the expensive audio cable doesn't use some special trick to force a sound difference. you also don't have an objective evidence that the expensive one offers the most accurate music.
so we don't know clearly what it does, why, or how. only that with 2 cables you got 2 sounds. if that is enough to convince you of the necessity to care about power cables, I'd say that you didn't need much convincing. ^_^
but most of all, we do not make rules out of limited anecdotes. we make rules from things we understand, or things that are so repeatable that we can predict the behavior even if we don't know why. finding one or 2 cables that make significant differences to the music, it's neither.
what is striking when I look at the people who talk about expensive cables who justify the expense, is how few objectivists are in that group.
shielding a power cable looks like a bad idea to me.
I wonder why.
A wire works like a antenna.
We do have a lot of EMI/RFI going on (WiFi, cell phone).
Shielding is simply putting the wire in a cage of Faraday.
Won't do harm imho
oh I doubt that shielding will have much impact on a short power cable anyway.
but in theory wouldn't the shielding add some capacitance? shouldn't that be seen as a bad thing?
and what do you figure the amplitude of the noise from wifi, cellphone etc hitting a power cable will be compared to the power supply itself? I'm guessing not much. and what about the power line and the wire running in the wall? what difference will the last few inches do? and won't most high frequencies be filtered or at least attenuated when the 220 or 110 AC will be transformed into whatever the device needs to use?
maybe instead of a bad idea, I should have said a waste of effort and good money ^_^.
