It's probably not the 25 foot coaxial audio cables, unless they ran 
parallel (and close) to power lines a lot of the way.  More likely is
that you have a ground loop; that is, 60 Hz AC is leaking into your
setup through improperly grounded power, antenna, audio and/or video lines 
and such.

When I hooked my Amiga up to my stereo in the living room as well as some
semipro audio gear I've got in the room with the machine, I had AC hum 
everywhere that took quite a long time to zen out.  It turned out that the 
cable TV feed was the culprit.  After disconnecting the cable I had a 
(nearly) quiet system.

Incidentally, for those looking for a hi-fi Amiga experience who want something
small, reasonably inexpensive and that sounds really good, I recommend the
Bose Video Roomates.  They cost around $200, come as a pair of stereo
speakers (one speaker has the stereo amp built in. It uses AC power).  Two
RCA plugs are provided for input; there's a master volume control on one
of the speakers (no balance). The speakers have internal sheilding to prevent
the speakers' magnets from damaging your monitor, tapes, diskettes, etc.
