Is an unshielded, unbalanced cable useful for anything in hifi? Where?



    Is shielding needed? If it is, shouldn't we all be using balanced cables wherever possible?  And yet, we hear that balanced connectors are only necessary, or usually even advisable, for long runs; that the added complexity may actually be inferior to an unbalanced cable in a typical 1 meter run, or run afoul of the particular implementation. 
     Is a cable "shielded" if it is coax, but the shield is used as the negative/ground (that is, connected/soldered to the plug at both ends?)  
   if a shield is tied to the negative wire at one end, isn't its capacitance "added" to the negative/ground wire, with potential deleterious effects?
   Yes, I know someone will invariably respond with, "rely on your ears," or "use the Cable Company", but random trials at significant expense seems like a poor approach. 
   not trolling the great cable debate, just seeking some guidance on what to look for in cable design, if any is to be had.

You have much to learn. 

All these things you're talking about, what you need to understand is as good as they sound when talking about them, in the real world you might as well forget about it. It may take you a very long time to realize this, especially with so many chanting technobabble in the echo chamber. But the truth is if you keep at this long enough, and learn to listen closely enough, and pay attention to all the techobabble stories, well then after a good long while what you will find is the stories are good- until they're not. 

What I mean is you will find one thing, and it could be anything. Could be silver. Could be shielded. Could be gold, copper, or silver gold and copper. Could be some super duper geometric weaving of silver, gold, and silver clad copper. Could be nano unobtainium ultra insulatium. Whatever. Does not matter. Point is you hear the story and then you hear the cable and gosh darn it that thing sounds good and so you conclude the story must be true. 

Until who knows how many months or years later you buy something based on the story and its a turd and an expensive turd at that and another one cheaper sounds much better even though dang it doesn't use the storybook magical whatchamacallit. In other words for every really good shielded cable you can find an even better unshielded cable, and on and on and on it goes for XLR, RCA, active, ground plane, you name the story I'll find you the exception that proves that wasn't it after all.  

That is why I must say sorry, but you really must rely on your ears. Because at least those tell the truth. The stories are all just that, stories. There's your real random waste of time and money: stories!   

What you do instead is forget the stories. Stories are for campfires. Focus instead like a laser beam on sound quality. Skim right past the stupid stories and read only the part of the review that talks about how the darn thing sounds. Politely ignore everything the sales man says and when he gets done blathering ask to hear it. Make him plug it in. Or buy stuff like Synergistic that lets you return no questions asked.  

Only way to fly.
