I agree with going to audio shows. Also, find some friends to borrow gear from. Once you have the speakers there are many different ways to power them: tubes, solid state, integrated, power amps, class A, class A/B, class D and more. You need to make sure that you have enough power to get what you need out of the speakers.
1 watt of distortion will blow any speaker but most speakers can handle hundreds of clean watts. Low efficiency speakers such as 86 db will take two to four times as much power to hit the same volumes as an efficient speaker rated in the low to mid 90's. So, if you find out that you love a speaker rated at 83db expect to buy those giant monoblocks. However, if you fall in love with 99db horns you only need to get 7 watts.
Finally, have a good reliable source that you trust with a couple of recordings that you know well.
