Okay, not actually nothing. I'm talking about the sound of an audio interconnect cable. Why pay $$$ for some funky interconnect when you can
DIY one using
Mogami,
Klotz or
Belden cables?
Here is my experience.
When I first studied electrical engineering, I was taught that a wire connecting two points (A & B) in a circuit and neither contributes nor takes away anything from a signal traveling between those two points.
After studying a little more, it turns out that wire has resistance. It also has capacitance and inductance. These parameters do not only exist at one point in the wire, but are distributed throughout the length of the wire.
More studying and I now have to contend with the fact that these distributed parameters contribute group delay to a signal.
Hmmm... this is starting to get complicated.
Group delay determines which frequency arrives at point B first. Ideally, they should arrive at the same time they started out from point A. But they don't due to group delay, and hence, we have something called frequency smearing.
One may argue that since the signals travel at the speed of light, having them travel a scant meter or two will not be detectable to the human ear.
Ahhh... but in addition to group delay, these distributed parameters can also interact with the signal and cause an effect known as filtering to occur. This usually results in some frequencies being reduced in amplitude, i.e., that cymbal that might sound real nice with one cable may sound indistinct with another.
We haven't even touched on the phenomenon known as skin effect yet.
Everything mentioned above is subtractive. What about additive effects?
As any student of science knows, passing an AC current through a wire results in it generating a magnetic field that is emitted. Another wire brought close to it will cause a corresponding current to flow within. Therefore, unshielded wires are subject to having nearby electronics influencing the purity of the signal flowing within.
So now a cable connecting points A to B in an audio chain is no longer just a simple cable.
When I started out with home audio, I spent lots of time and effort buying all sorts of cables from Sim
Lim Tower and fashioning them into various interconnects used to hook up my
hifi system. After all, a
DIY cable made from
Klotz wire and
Neutrik interconnects (total $80) should sound as good as those costing hundreds of dollars right? WRONG!
After a year with
DIY interconnects, I borrowed a friend's
Tara Labs Reference Generation 2 cable and stuck it into my system. The impact of this switch reverberated in my eardrums. The sound had more air, better separation, better focus, and larger
soundstaging. Only problem is that this cable retails new in Singapore for $480.
Putting that old
DIY cable back just didn't cut it anymore once I've heard something close to audio nirvana.
Next week, I'm ordering a set of these from the US, which will end up being cheaper at $350. No more messing about with
DIY cables.
Will I be satisfied with the sound now? For sure... that is until I try out those $1500 Audience AU24 cables.
