Good grief, Charlie Brown, no one answered Mrtennis's question.
Do this: Find out your interconnects capacitance rating in pFd per foot. This will be a number around 10 to 250 pFd or so or maybe more if you have high capacitance cables.
Multiply this number by 19.7 and then put that number for C in this formula:
fc = 1/(3768)(C) This will give you the upper frequency limit with a 600 Ohm output impedance from the cables point of view. What you have downstream or upstream of this may impact the fc substantially more.
Of course, what it sounds like below that frequency point is another issue, but I assume you like the sound or you wouldn't be asking the question. But, your sound will drop off rapidly after that fc point.
In general, you are better off moving signals into a high impedance over distance than a low impedance over distance, so longer interconnects have an advantage over longer speaker cables. This is very general, though. What you may own may change this completely.
