I went into Richer Sounds a couple of weeks ago to demo the BA Soundware and Q Acoustics.
Personally I preferred the sound of the Q Acoustics, but the salesman also hooked up the Kef 1005.2 system which was more expensive at £400. I found the sound more powerful with more active rears when deming with Avatar compared with the other two. In the went for the Kefs and went £100 over budget, but the increase in quality was well worth the extra £££.
Having said that the BA's do a good job of filling a decent sized room, but the larger Q Acoustics (for £30 less) sounded better IMO
