Atmasphere,
You gloss over many things that are not obvious (or intuitive) to the casual reader. I'm not restating to tell *you* anything you do not already know - just want to make sure everyone following understands the differences (subtle, yet very important). This topic seems to cause a bit of confusion.
A "balanced" cable has nothing to do with the termination (XLR, RCA, bare wire, etc.). As Ralph said, a single "balanced" cable has a specific wire geometry - two identical leads (one positive, one negative) surrounded by a shield (ground). *Usually" a balanced cable is terminated by XLR, but you can't be sure without looking "under the covers". But this is the same with amp / pre-amp design - you can't assume it's a balanced design just because it has XLR inputs / outputs.
While many arms ship with a 5-pin DIN connector (and makes it easy to swap in a truly "balanced" cable), my OL Silver did not. I did not want a DIN connector as I wanted a continuous piece of copper from my cartridge clips to my XLR terminations. Unfortunately, OL does not ship the Silver with a "balanced" cable, even when requesting a "balanced" tonearm (they just slap on XLR terminations on their single-ended wire, then charge you £330.43 plus £21.74 for new XLRs fitting for their Linear Flow 2 cable if you want it truly balanced).
