I'm with Kal - I use Fuzzmeasure and a measurement microphone - examples are on my virtual system. Even with a tool like this it took me several days to make adjustments. A good understanding of physics helps but is not a prerequisite to using tools like Room Eq Wizard (provided you read up on the subject).
If your idea of system tuning is swapping out your $500 speaker cables for $1,000 speaker cables in order to match the brand of your $500 interconnects then simply ignore this post. (There is absolutely no point in taking measurements if you are not prepared to take appropriate action to do anything about it - in that case it may be better not to know and you'll have more fun spending your money on some cable elevators instead)
