Balanced interconnects and non-differential amps


If one of the generally accepted benefits of long runs of balanced interconnects between a preamp and an amp is noise rejection, is this still true whether or not the amp in question is a differential unit? If not, is balanced no better (for noise rejection, with all other things being equal) than unbalanced runs of the same length?

Thanks.

Thanks so much, Al.

Here's what prompted my question: I've been looking into the Odyssey Audio amps, and read the following in a 6moons.com review of the Kismet monoblocks: "On the input side of the amp, the Kismets come fitted with XLR receptacles although these are provided as a convenience for those with balanced line-level cabling. The amp is not a differential design. Internally Groneberg’s Quattro Reference New Generation cabling connects the line-level inputs to the first stage of the amplifier."

As I'm nobody's electrical engineer -- my knowledge of such things is quite sketchy, in fact -- I wasn't sure what exactly to make of this statement. And it got me to thinking, and wondering about balanced connections more generally. I appreciate your answer -- and the link.
