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.

Unless the all the equipment you buy has electrical interfaces for balanced line interconnects, you can't use them anyway, so don't worry about it.

For home audio equipment balanced interfaces are a high cost "boutique" feature. In pro sound equipment, where balanced line have a real technical advantage, they are routine, and add little to cost.
