What is the benefit of balanced xlr cables


I just bought a marantz av7005 that has balanced outputs for xlr cables and I have a b&k st 125.7 s2 to hook it to also have a older Cambridge audio cd6 that has balanced connections on it.what are my befits to switching to these cables over my rca stuff.What is a good brand without breaking the bank,I've used blue jean cable,kimber kable,and synergestic THX

For me it depends on the RCA or XLR electronics and the quality of the RCA or XLR ICs not whether it is RCA or XLR... that's how I hear it :)

Unfortunately, XLR electronics remove 2nd order harmonics as part of the XLR noise filtering/cancelling process, which our ears like, but leaves the 3rd order harmonics in place including the noise, which our ears do not like... :)

If the Hot and Cold XLR electronics is not well matched then the noise filtering/cancelling process can be even stronger where even more 2nd, and even 3rd, order harmonics are removed. I guess that will provide a smoother, maybe warmer, sound :)

Copper is more forgiving in sound than silver. But the best silver cables can reveal a lot more details than the most expensive coppercables.
Really? If I lived in your area I would be more than happy bring along my Jorma Statement speakers cables to a-b compare to any silver speaker cables you care to throw at them.
I will ask the distributer ( in the Netherlands) of Jorma to bring a few cables with him. I do business with him and I know him for a long time. He will visit me in 2015. I will email about the outcome. I have no experience with these cables.
