I'm sort of new to the whole HiFi game as well. I've always loved music and share similar tastes to what you have mentioned. I have auditioned a pair of Revel M106s and they rocked. Great clean low end and very crisp, but not too bright, highs. They are a little above your price but if you can find a preowned set they are great. I have a set of Nola Boxers. Same deal as the Revels. They don't have quite the punch on the low end but handle rock really well, very crisp highs without being too bright and enough clarity to clearly differentiate the different instruments in a song. They also have a higher sensitivity than the Revels so you don't need as much power to make them sing. I am actually looking to sell my Nolas if it is something that interests you. Good luck with your search and I understand your dilemma. There are just too many great choices out there.
Cheers
