Nrenter, Its a fact that there are cable guys out there that have no idea how to execute balanced cables, especially ones for phono!
Most arms that have a 5-pin connection are perfect balanced sources, as the wires are shielded by the arm tube itself. This includes all the old BSR, Garrard, Dual and other inexpensive 'tables from the 60s and 70s- they are very easy to convert to balanced without any mods to the arm at all. With newer arms that use the 5-pin DIN, its easy- just change out the cable.
In fact it is even possible to set up an arm with RCAs for true balanced operation, as long as there is a grounding post and the RCA jacks are isolated from ground. We make a special cable for that. It can't be done if the arm ground is tied to the minus of one channel (which causes a ground loop), like you see in some air-bearing arms. BTW it is this ground loop issue which is why most arms employ 5 wires (the 5th for ground) rather than 4.
