Five "Golden Rules" of HiFi?

My five are similar to yours, with a couple of modifications since I have had excellent experiences purchasing used speakers, and most of my purchases have been of used equipment that I couldn't listen to first. Here are my 5;
1. Protect your hearing,
2. have fun and enjoy both the eqipment and music aspects of this hobby,
3. interact with others about your system and music,
4. don't overspend, rather build a system within your budget that sounds good on your music, and
5. maximize system effectiveness - through room treatments, vibration management, and clean, protected power.

1. Research gear and set a reasonable budget accordingly.

2. Listen to as many live performances and audio systems as your can to help develop your ear and define your tastes and priorities.

3. If possible, connect with an audiophile/music lover community, preferrably local and/or online.

4. Determine whether you're a last 2% person, be realistic with repect to your given room and system components.

5. The room can be half the battle.

1: Focus as much time and effort to learn about new music as you do the music system. Afterall, it's all about the enjoyment of the music. Without this, what's the point to all the madness of assembling a system.

2: Learn to enjoy what you have rather than constantly being self-pressured to make changes/upgrades.

3: Keep an open mind. We often have expectations on how a component will sound or compare to another only to have the outcome be quite the opposite.

4: Network with other people in the hobby. There is so much to learn through friendships here.

5: Every link in the chain is an equal. Some links may take more time for us to find the "right" piece, but each can only perform at its best if all else is there as well. The result is a well-integrated system rather than simply an assembly of pieces.

I really like what Jafox say's above. I think it's real important to educate yourself about new music, or old music that's new to you, as it is to be obsessive about equipment (for me anyway).

I like the idea of hearing as many different systems as possible to educate yourself on the presentations you prefer too.

1) Make sure you are listening to music, not sounds. If you don't love music, you are wasting your time and money.

2) A system is only as good as its rooom. Spend as much time as you can optimizing placement of speakers and components. Moving a speaker 3 inches can change the sound more than a new pre-amp!

3) If at all possible, buy it used. This especially applies to cables and cords. It probably does not apply to analog cartridges.

4) Understand the technology and it's strength's and limitations. If you have a tube amp, understand how to properly bias the tubes and when to replace them.

5) Trust your own tastes, realizing, in time, your system should reflect your musical values. A person who mostly listens to String Quartets will most likely end up with a different flavor than someone who is into heavy metal. This is ok., no one has a system capable of reproducing a live perfomrance perfectly, they are all colored to some degree, and that's just fine. You know, some people like chocolate, some like vanilla; neither of these is "right"
