Agree with Al. Balanced helps with ground loops as well as EM/RF. Balanced also
runs at a higher signal level so it improves S/N. Balanced amplifiers are usually
found in pro grade gear and can usually handle tougher loads with higher
capacitance cables and longer cable runs without signal degradation. Some RCA
grade gear is pretty bad but most should be good enough that it won't make a
big difference. The more gear you have and the more connections you hve and
the longer runs you have the more likely you will benefit from balanced.
