What is the advantage of a balanced interconnect?


How does a balanced interconnect work (perform) as opposed to a regular interconnect?

I've been out of the "market" for a while and am a little behind. It seems "balanced" is better; however, one guy told me that unless I am running long lengths I don't need to worry about balanced interconnects. Equipment would be NAD or Parasound CD Player, undetermined DA Converter (the $3,000 question), tube monoblocks, and Magneplaner speakers (probably just 1.6's). [I think I hope to purchase a DAC with a volume control and run the interconnect directly to the amplifier - no pre-amp. I think.]

A quick primer on balanced interconnects would be appreciated. Thanks

Nothing unless you have runs exceeding 15 feet or a weak signal from your preamp or an ungodly amount of electrical or radio interference in your area.

This is a beaten-to-death thread, so don't be surprised if you don't get a lot of replies.

I have used both, and the only time it made any difference was with 5 meter runs from preamp to amps.
