That's a good receiver you have. And being a good receiver, there's a million speakers to be had for that price that will sound great with it.
My advice is this- repost your question, and re-word it- this time, mention your amp, and mention your $150 budget, but instead of asking what sounds good with that amp specifically, ask for recommendations for a good speaker for the type of music you listen to (and let us know what type that is), your listening habits, the size of your room, how far/close you'll be to/from the speakers, the volume you'll be playing them at, if you'll be running a subwoofer, and the size of speaker you want.
For $150, If you want a largish bookshelf speaker and an "east coast" sound, and for classical, folk, country, some rock, ect... I'd look at Polk Monitor 7s/Monitor 10s, EPI 100vs, ADS L420/L470/L570s, Boston Acousics A70s and the like.
If you want a largish bookshelf speaker and a "west coast" sound, and listen to hiphop, hard rock, techno, ect... I'd look at JBL L46/L56s and Pioneer HPM 60s, and similar.
If you want a smaller, yet still rich sounding and powerful mini-monitor speaker, then check out an NHT SuperZero/SuperOne or a Paradigm Atom/Titan, for reference.
