FWIW, I have a pair of Dali Helicon 400's in a smallish room, and they sound quite nice at low and mid-volume levels! I have a CJ PV-15 pre-amp feeding into a JWN tube amp, which has 8 el34 output tubes. Lance Cochrane estimate it at around 100 watts per channel. The amp itself has a higher sensitivity than my old solid state CJ AMP, and it controls the bass better as well. I get an incredible soundstage with lots of three dimensional detail. Something about the ribbon tweeters in the speakers makes them sound almost like panels in the mids and the highs, which are to die for.
I have the speakers around 7 feet apart, and I sit about 10 feet back.
