I'm not trying to get you to change your rules.  I completely agree with 
them.  The problems the article discussed with digital cables really 
only occurs on very long runs--for exactly the reasons you've 
described--the cable either works or it doesn't on "normal" length 
runs.  And, since long runs are the exception (not the rule), your rules 
definitely stand up.  (Especially since someone doing an extremely long 
run will likely have problems regardless of which cables they buy.  So, 
your rule will save them a fortune that would have been wasted on a 
name-brand cable that wouldn't work, either.)

Agreed.  As a matter of fact, as discussed in the article, coax is 
perfectly suited for transmission of digital signals because of its 
impedance characteristics.  If the impedance is right, the cable works 
great--regardless of how it's marketed.

I've been a believer since I first saw the "Max Rochlin Memorial Cable" 
( http://www.enjoythemusic.com/etmcable.htm ).
