Balanced vs Unbalanced?


I am vaguely aware of the scientific merits of "Balanced wiring". I am only interested in the "Audio" merits.
CJ, a company that makes some of the best equipment on the planet, has no "Balanced" equipment that I know of. This puts some doubt on the audio merits of this circuitry. What is your opinion.

IMHO, Audio merits are based on scientific merits. There is no magic here.

BTW, this topic has been debated for the Nth times. Search is your friend, my
friend.

According to McIntosh's manuals with their balanced gear, if your interconnect cables are 6' or under, unbalanced connections are quite satisfactory. However, longer than 6', a 40db advantage in noise reduction is possible. Whether you can actually hear any difference between the two types is subjective.
Here's another one--why is McIntosh the only company to use autoformers, when other companies (i.e. CJ) don't use them? Any sound differences?
