I find that using shorter speaker cables lessons the ability of the cables to actually physically reach to the location of my speakers, resulting in a distortion-free, low noise, utter lack of any sound at all.
Speaker Cable Different for 8ohm vs 4ohm
What is the impact on speaker cable when using a 4 ohm speaker such as a Magnepan 3.6 vs a typical 8 ohm speaker. I have read that when using 4 ohm speakers that it is a good idea to keep speaker wire runs as short as possible. Of course, wouldn't it make sense to keep speaker wire runs as short as possible in any case?
