Do no harm to a signal! Does this mean.....

Yes really.

You want an IC to roll off the highs, you increase capacitance by putting the conductors closer together. You want speaker cables to roll off the highs, you increase inductance by spacing out the conductors. There is no magic.  However, doing either is highly system dependent, and almost always if you take your eyes out of the equation, not audible.


Some like Transparent add some cheap passive components to the cable. Some claim that adding a bias reduces noise (though the opposite happens). Some make claims about ground blocks, but can't seem to prove it.

Does anyone understand what happens to an analogue signal when it flows thru a speaker cable??

and challenges in transmitting a delicate analogue signal???

substance please

Does anyone understand what happens to an analogue signal when it flows thru a speaker cable??

Sure.  The resistance, capacitance, and inductance of the speaker cable all have effects on the signal.  

How dramatic those effects are depend on the type of wire (copper v aluminum v silver etc...) the thickness of the wire, the length of the run, the proximity of the two conductors to one another, the quality of the insulation... 

Tons of factors.  Each one changes one value over another.  Some matter more than others.  *There is no perfect solution* is the most important thing to remember.  Just solutions that prioritize one value over another. 

Heavy gauge wire decreases resistance and inductance, but increases capacitance. Light gauge decreases capacitance, but increases inductance and resistance.  

But there's more:

Speaker wire crossing another electrical cable (power, interconnect, etc) has a deleterious effect on the audio signal.  Because now the two electrical signals are interacting with one another's magnetic fields. 

There are so many variables, essentially there's no such thing as the "perfect" cable.  It's all give and take regarding your signal. 

"...Isnt this the reason for paying up for cables cause,its so hard to limit signal damage?..."

Audio cables are deliberately designed to change the sound we hear. Common measurements are conductivity, capacitance, impedance, and resistance. Audio cable's job is not to be the perfect conductor, it's job is to improve sonics in a particular way. So some parameters are changed to accomplish this.  

Drugs?  Cure?  
Personally I'd feel a lot better without all the idiotic meds commercials.
