Best small speakers?

I'm looking for great sound at the best price... spending around 5K, am i going to get better sound and with small monitor speakers like the B&W 805's or Harbeth? I have Paradigm S-8s now... they are big sound alright, but i think if i spent the same money on a great smaller speaker i would get more for my money as far as sound goes... ? I have an above average system, rouge 180 monoblocks, shanata cables, conditioner etc.
