Heres some more food for thought -- I agree with the voltage references in 6bq5's post, BUT part of the analysis could lead one to perceive the wrong solution... Termination at line level is typically 10K-200K ohms; At the speaker, the termination is typically .5 to 20 ohms, depending on the frequency and mostly the speaker. Therefore one could conclude that the resistance of cable created in long lengths has more effect on the lower resistance termination, due to the increase in current in the network. When current is limited by resistance in cable, amplitude will also be limited. In most cases, reducing dynamics and resolution. Personal experience and theoretically speaking tells me that short cable lengths are more important for speakers rather than interconnects.
