Top 10 Snafus to avoid when building a good rig

Attributing sonic characteristics to components or cables that are in fact the result of INTERACTIONS between those components or cables and what they are connected to, and/or other parts of the system.

Seconding Ahendler's comment, I believe that kind of mis-attribution is a major reason for over-reliance on the opinions of others, because it can result in unfounded expectations that the reported experiences of others will be consistent across different systems.

Listening to others opinions rather than trusting your own ears

Gotta go with this one too.

Falling for the first pretty faceplate that comes along.

Convincing yourself that a particular component is going to be the holy grail, thus justifying spending more money on it than it is really worth or can be resold at.
