New audiophile looking for first speakers. HELP

Hey guys,
I am looking for a good pair of speakers for my first audiophile system. Right now I have a Stanton ST-150 table running through a Mackie mixer running into 2 Behringer Truth 8" studio monitors with a 10" KRK sub. I am looking to begin building my first audiophile system. I am mainly focusing on vinyl, and maybe get into cds later on. So far this is the equipment that I have decided on:
Mesa Boogie Baron Amp
Rogue Audio Metis Preamp

I will probably keep my turntable for a bit but, I have considered a Clearaudio emotion.

I have NO idea what speakers would be a good fit.

Mainly, I will be listening to aggressive metal ie. black/death metal. Also some electronica, rock, and classical stuff. Mainly aggressive stuff with pretty wide frequency ranges.
Please give me any suggestions possible. Thanks in advance guys.
