Man there are so many awesome speakers and they all have their own sound.
I would recommend a couple options.
1. Go to Deja Vu audio in Fairfax (
http://www.dejavuaudio.com/) They specialize in tube technology therefore their speakers are all made to deal with the low wattage of tubes. Basically that means they are they are really efficiently built and will make better use of your wattage in making volume. They carry INSANELY expensive stuff but they also have stuff for the rest of us. Even if you don't buy anything there you need to see this place. It will change your fundamental concept of audio technology.
2. Buy Canadian. The Canadian government sponsors some audio research so many of these companies make better products cheaper. Ones I have experience with are:
Dahlquist (
http://www.dahlquistcorporation.com/) (I own and love)
Mirage (
http://www.miragespeakers.com/) (I own and like a whole lot)
Paradigm (
http://www.paradigm.com/) (good speakers for rock, lots of bass)
Energy (
http://www.energy-speakers.com/) (I remember these being good but haven't heard in a while)
Some of these are at Myer Emco

Of course there are obvious concerns when buying this way but great speakers like these just get broken in better over time if they are taken care of and you are getting a great deal buying used. I LOVE KEF but it is all personal taste really.
Just listen a lot. If you go to Deja Vu, when you leave those Bose will sound like a distorted guitar amp.
Of course once you get some good speakers then you are going to want to drive them better. Okay, I'll stop. I know I am an audio geek.
