[Elecraft] [K3] Audio circuit distortion

[Frank Precissi]

You have got to be kidding me:

http://www.revolutionpower.com/p/Oyaide+Li50EXs+Power+Cable+1.8m/151/

http://www.revolutionpower.com/p/Oyaide+Tunami+GPX-R+004+Power+Cable/274/

Its to the point where it blurs the line between over-the-top serious and a
joke.  $500 power cable to feed mediocre caps and transformers in an amp.
