CrashmarsThis is a tough question to answer as you have not listed your amp nor source. Something like a Klipsch Heresy can be purchased used for your budget and rock the house with a flea watt ebay amp. On the other hand, some speakers, for instance some versions of Thiels are going to require many thousands of dollars in amplification. Location would help as someone with time and inclination might look on your local craigslist and make a recommendation.
