I too wonder whether neutral is really the best term. To me the issue is that power cords do something to reduce the grain structure that mains-borne noise imposes on our music, and also alter the grain structure. When the grain structure finds harmonics with the music it accentuates that part of the spectrum - which in turn causes a sense of brightness, darkness, harshness or sweetness. I have played around with power cable design and construction a bit and suspect that this is what is happening. First issue is to reduce the grain, second issue is to get a grain structure that interferes with the music least. I respectfully disagree with Brulee - I regularly go to our local concert hall and lament how it destroys the vibrancy of violin and brass tone, and go to my local jazz haunt and have a very slight cringe at the relatively bright acoustics, yet welcome the fact that it contributes to capturing the energy of the performers.
The best Neutral Power cord ?
I am looking to upgrade from the stock power cords on my amp, DAC and Preamp. First of all, do power cords really make a significant difference? If they do, what is the most neutral sounding power cord in the $100-300 range (used price of course. Do you have any suggestions? Please help.
