Balanced vs Single ended?

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.

Thnak you to everyone for your answers. I'm runnibg an integrated amp to my CD with 1 mtr single ended ICs, they were built to be matched from Ridgestreet Audio. I was wondering if using Balanced would provide still an even greater degree of definition and resolution for me which you all have answered for me very well. As far as noise floor goes I also use PS Audio Noise Harvesters at each outlet which gave a (for me) dramatic difference in presentation. At worst the longest run I'd ever be using is 1 mtr so I guess I'll be Ok then. Agaain Thank you everyone for your help.

Some feel that single ended is more natural and musical than Balanced. A lot of it will depend on the design of your gear and what is recommended.

If you live in Manhattan and you have to use a 7m interconnect, than you have to go balanced.
