there have been many suggestions as to what not to do when buying components. i have been thinking about the essence of the theme--namely avoiding mistakes.
i've come to the conclusion that one cannot avoid making mistakes. to err is to be human.
so, i say, do your own research, learn from your mistakes and don't worry about violating the conventional wisdom.
building a stereo system is not like crossing the street directly in front of an on-coming vehicle.
there is no right and wrong, only what sounds good to you.
