If you are on a budget, do your research before making any impulsive buys. If you listen to music through speakers, treat your room acoustically a bit (it can be done quite cheaply) and study what digital room correction is and apply it (it can be done for free - use MathAudio or Room EQ Wizard). Learn about speaker placement and speaker-room interaction. This knowledge will save you a lot of frustration and a lot of dollars. If you listen to music through headphones, educate yourself about crossfeeds and find the one that you like best. A crossfeed technology is the most important discovery in headphone industry. It's the major breakthrough in this area. Sadly, it's ignored by too many "audiophiles". Knowing these things can cure many of audiophilia nervosa because when you know the technical side of this hobby, you can make a modestly priced gear to sound better than a more expensive one.
