-no real world experiment has been conducted whatsoever, and somehow ppl want to convince themselves that everything sounds the same...you know, the same kind of thread that says that a $100 DAC and a $1K DAC are impossible to DBT on transparent headphones
-low end gear was used
-the testers either aren't trained for analytical listening or have hearing problems.
if all USB/coax/toslink cables sounded exactly the same, this would be such a wonderful world \o/
OTOH, the major issue is that some sellers obviously make 2/3 figures markups...they make you pay for their trial and error at finding the best sounding cables(to them, which might be a different story for you...YMMV as usual in the audio world).
IMHO and IME, the best cable is the shortest..less signal attenuation and less interferences/jitter. And my best sounding cables were cheap too. It's not because all cables sound different that a $100 USB cable will sound better than a $5. It's all about build quality and synergy.
The problem w/ snake oil cables is that those companies need to provide a lot of free review samples and bribe (british?) audiophool magazines to backup their bs arguments. You're paying to be conned basically.
Digital signals are very fast sinewaves, not quite 0's and 1's only. A million things can go wrong in a digital audio cable, believe it or not: http://en.wikipedia.org/wiki/Coaxial_cable#Issues
And unlike HDMI, USB audio and S/PDIF don't use ECC...what's lost *is* lost.
