Is there a difference in balanced cables??

You may want to search AudiogoN's archives.

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,

I have written extensively here the last several years on my experiences with various XLR cables from Cardas, SilverAudio, Audioquest, Transparent, NBS, Kubala-Sosna, etc. There has been a huge difference with each of these along the way of continued system refinement.

Do a search for any of these brands, as well as Purist Audio and Nordost, and you will get a good idea as to the pros/cons of these cables in the context of varying levels of music systems.
