Dan of dansdata.com linked to this fantastic thread on head-fi.org.
Long story short:
1) Chap receives 'free' $150 audio power cable from manufacturer representative on the forum, having paid $20 shipping.
2) **CAT ATTACK**
3) Chap surveys wreckage and realises that cable is made of standard components, and shoddily at that, so posts picture on forum and invites discussion.
I'm on post 170 at the moment, and it's getting funnier and funnier, with the manufacturer and a couple of 'golden ears' posters defending expensive power cables to the hilt.
Just wait 'til you get to the manufacturer's awful attempted cop-out of "oh, this cable we sent out free isn't actually representative of the ones we'd make you pay for".
