Speaker pairing for audiolab 9000 series

I'm looking for a speaker pairing for my system.  The system is bridged (2 amps).  I currently have klipsch heresy IV's,  but just don't love the sound.  I know there are many variables involved, but let's just assume everything is perfect.  I don't need to burn the house down, but like to turn it up a little bit sometimes.  I'm also not a millionaire.  TIA for any insight.
