"If you measure the frequency characteristics of certain RCA cable, you will be
surprised by the result. In one meter of RCA cable, the 100Khz frequency
degrades about 3 to 4 db."
Really, that statement is just misleading. And who cares about 100 Khz in audio apart from engineers? Can people hear frequencies that high?
|6. If you measure the frequency characteristics of certain RCA cable, you will be surprised by the result. In one meter of RCA cable, the 100Khz frequency degrades about 3 to 4 db. This is due to the stray capacitance on the cable. So if you run an audio signal through a two meter or even three meter cable, the sound picture and dynamics will be darkened by at least 5% compared to a shorter cable.|
A cheap and simple cable test for anyone who wants to see if there is a difference between cables simply needs to have an HD600 or 650 and the cords for both. $20 cable expenditure max. Go back and forth and see if you can hear a difference.
Honestly, I don't know the actual science behind why cables sound different, but they do. Different metals have different conducting properties and they have different purity levels as well as design structures, so maybe all of those variables go into ultimately affecting the sound...
I bet if you did a test with the same amp using different tubes, you probably wouldn't get very different results between tubes, yet it's pretty commonly accepted that tubes can alter sound.
Also, it ultimately comes down to what you hear with your ears. I don't know anyone who can look at a graph and say, hey, the AKG K701 has a wider soundstage than the Sennheiser HD600, but the Senns are tonally more accurate. To find out some information, you'll simply have to listen to it yourself. I recommended the Senn cable test, because it is cheap, and although the different isn't absolutely huge between the two cables, it is noticable.
