Top 10 Snafus to avoid when building a good rig

I agree with the sentiments and philosophy of Marcojack, Whart and Swampwalker. Over emphasis on the quest for perfected sound can detract from the importance of the music and reverse priorities. I do believe that more enjoyment and long term satisfaction comes with focus on the music you love. I'd rather listen to music and become involved with it instead of analyzing, dissecting and critiquing the sound. It seems components should serve the music and not the other way around.
Charles,

1) Forgetting to treating your room acoustically so you know how your rig sounds.
2) Spending too much on cables so you can't buy a decent amp, preamp or source.

Snafu No. #. Placing the speakers too far apart.

Start with speakers about 4 feet apart and slowly move them further apart.

Cheers
