I'm thinking about upgrading my speakers, and have about a $300 budget. I will mainly be using the speakers for listening to music, particularly rock music (like the strokes, sonic youth) but also some bass-heavy dance music like dubstep, but still be dynamic and bright enough for bands like Radiohead, so you can hear the nuances of the music as well. I live in an apartment in New York, so I don't want to buy a sub. Any suggestions for floor standing speakers? Thanks.
