My way of thinking goes as follows:Low level signals (interconnects) are closer to the source material and are more susceptible to greater outside influences. This can be attributed to signal degradation due to line loss, greater susceptibility to RF interference or magnetic fields, etc.. Remember, we are trying to reproduce the source as accurately as possible. You have less voltage and current to work with at line level, so ANY loss is further compounded and amplified down the line.
A very SIMPLE analogy would be this: The source (cd / tuner / dvd, etc) generates appr. 2 volts of signal. If you were to lose .25 volts along the way due due to resistive losses (connections, line loss, etc) the best you could possibly hope for would be an 87.5% accurate reproduction of the source (given these circumstances). Now look at the same losses attributable to resistance AFTER being amplified. If we use a low voltage as a reference level coming out of the amp (10 volts), losing .25 volts is NOTHING in comparison. This is 1/40th the amount of signal loss compared to the line levels 1/8th ratio of loss. Which do you think would be more noticeable ?*
The amp can only reproduce what is put into it. If the signal has already suffered mass loss or degradation before going into the amp, what would you expect out of the amp ?
Speaker cables are much lower resistance and better conductors than interconnects. They offer lower losses in every aspect. They deal with much greater levels of energy to transfer the information. They carry information that has already suffered every form of degradation to the signal possible and are last in the reproductin line of cables (farthest from the source). They are therefore the logical choice to use when longer runs of some type of cable is necessary. All this being said, they can make a MAJOR difference in the sound of the system. Sean
