Is there a difference in balanced cables??

Yep, I searched the archives. Lots of threads about balanced vs. single ended. I did not see anything concerning difference in quality or sound from one brand to the next. If there is a difference, is it clearly noticable?
I remain,

Great responses! Now I know the balanced cables could and probably do matter. However, with such diverse opinions here I have to believe the difference is subtle. Especially to my untrained ears. I am in a major digital front end upgrade phase at the moment. I plan to focus on all cables once my gear is revealing enough for me to really hear the difference ( or not). The folks at Blue Jean really played down the need to spend big bucks on balanced cables. I just wanted to see what the 'Gon community had to say about it. As I get further into this hobby I am finding there are no absolutes. Only what you hear for yourself.....or think you hear. Thanks for your help.

When I first started reading threads here a year ago I thought you guys were a little nuts comparing the sound of a piece of wire and putting out mega bucks for the flavor of the month. I mean.....wire is wire, right? Then came the whole power cord thing. At that point I was CERTAIN you were all as nutty as a squirrel pantry! However, I am starting to be a believer....so what does that make me????
My new components should be in place in the next few weeks. Then I can do some serious cable comparisons. Actually, I have been wanting to get to the bottom line on this cable thing for quite some time. The suspense is killing me!
