Having gone balanced I would strongly recommend any who has truly balanced gear to try it! For all the reasons the other members shared above- it is a better method of signal transfer on the right equipment.
balanced cables
What exactly do balanced cables do, and is there any difference in sound quality? What is it that gets "balanced"? I'm in the process of buying a new(used) Mac amp and preamp, and the literature says they accept balanced cables. Is this to connect the two pieces? I'd really appreciate having some light shed on this question. Thanks.
