Can someone explain the difference between balanced TRS cables and regular stereo cables, and a good place to get them? These would be for connecting a Behringer mixer with balanced outs to an Echo Mia.
Thanks.

Thanks for the replies and links. Still, I'm not clear on the distinction between "balanced" cables and "stereo" cables as far as the way they're wired. The Hosa Cable site uses the terms interchangably:

Also, balanced cables seem to be priced higher than regular TRS stereo cables. As long as they're wired the same is there really any difference?

I'm not sure what's new in patch cables but i'll be needing a bunch of various patch cables myself soon and have a basic assumption/requirement:
How the cable is wired depends on whether the application is for a stereo signal or for a balanced signal. In either case the connector is the same though.
Balanced refers to a mono signal that is diferential, or expressed as the difference between two signals. The cable itself will normally be a twisted pair of wires within a single comman shield.
Stereo refers to discreet signals, one for left and one for right, and the cable should consist of two isolated wires within their own shield to maintain channel isolation.
At the risk of some crosstalk i guess a balanced patch cable could be used as a stereo patch cable in a pinch.

With something as short as a patch cable, you'd be quite hard-pushed to measure the crosstalk difference between twin and single shielded, never mind hear it!
As long as they lay together, twin screened cable is fine for balanced connections as well as stereo ones. In fact, the best balanced cables you can get, which are star-quad ones, have each of the individual signal leads screened, and an overall screen as well. It may look as if you could use these for balanced stereo, and you can, but the original intention was to connect the opposite pairs together, and just use the cable as a mono balanced line with enhanced rejection properties - hence the name.
