I've just converted to a low powered setup in a small room. I'm using Omega Super 3XRS speakers (94db)which replaced a setup alternating between Kef LS50's, Harbeth P3's and Silverline Minuets. I couldn't be happier with the sound. Super coherent, very fast with great imaging/soundstage capabilities.
The Omegas have plenty of power and then some for my 4 watt amp and they meet your budget requirements.
