5 things I will not do agian, what about you?

A post on Audio Asylum about weather you would start over or not if someone paid you what you had paid for you equipment made me think of 5 things I will never do again. Do you have a list to share? Of course we all know the danger of saying never.

1. Buy speakers that have to sit 4 to 6 feet out into the room.
2. Buy speaker cables so big and heavy they break things and make me want to curse.
3. Buy separates, integrated amps and power amps with volume control or power amps with attenuators are just too good, and you don�t need another power cord, another set of interconnects, and another power isolator.
4. Try to combine a Home theater and music system into one. This one I might some day have to do out of necessity but then I would just plug the TV into the two-channel system and enjoy.
5. Ignore, the room, vibration issues, power cords, and conditioners.
