Well, I read Mr. Mackie's article, and for starters, he apparently is unaware that "ground" in a SE circuit is "common ground" or "chassis ground" whereas "signal ground" in a BAL circuit is separate from the common/chassis ground, and therefore presents a different (and quieter) reference for the signal. If you look closely at an XLR connector, you will see it has two separate ground connections: signal ground (usually pin 1) and common/chassis ground provided by the bayonet connection on the barrel of the XLR.
This is another way balanced circuitry provides cleaner signal processing. I'm sorry, but I believe Mr. Mackie's article contains misleading information which in the end compromises his conclusion(s). Just my opinion of course ;~))
