How do I know if seller is selling genuine cables?

Well if they have the original receipt from an authorized dealer.
that would usually be a help.
Though if a person wanted to sell fakes, making up a phony receipt would not be too hard to do.

The fake cables have really put a dent in used cables IMO.
I am lucky I just do not need any cables.
The last cables i bought new from a trusted local dealer, so i would be certain it was a genuine product.

This is a real problem, I've now seen over a dozen fake Audio Note Japan cables that people paid good money for.
All I can say is BE CAREFUL !

Is it just me or are there always alot of Audioquest Sky for sale on this site at really low prices? They almost never have a box with them (unless priced higher). I have wanted to try the Sky but am skeptical of the fakes. Someone may have great feedback here on Agon but may not know the history of what they are selling. Is great feedback enough to accept the cables as the real deal?

I'm a fan of supporting the companies that sell direct. Signal Cable, Morrow, MAC, and Audio Art are just a few examples. The pricing on most of their cables is generally about the same as a used cable of a similar quality from a brand that uses a distribution network and advertising. Plus, most of these brands offer at least a 30-day in-home trial.
