I'd even go so far as to advise people, where feasible, to think of replacing a conventional stereo power amp with a pair of monoblocks. I got the benefits Rute specified in a big way when I changed from 7' speaker cables to 18" ones. But even dropping one third of the length of a 15' pair will be beneficial, and let further upgrading show its benefits.
Speaker Cable Length
I know that this thread has been visited before in gerneral terms, but I would appreciate feedback relative to my specific situation. My current speaker cables are 15 feet each. What, if any benefit, will result in using 10-12 feet lengths? What about 8 feet (the shortest I might be able to go after extensive re-arranging of equipment)? Thanks in advance.
