I agree - different speakers. I prefer the Aerials though the Dynaudios are right up there. The Aerials are more articulate with tigher bass. "Tuneful" bass as a friend says. The Dynaudios are warmer with more bass punch. IMO, the Aerials are more solid and better built but the Dynaudios again aren't far behind. If you were going to get the 9s, why not move on up to a pair of 20Ts vers 1. I've seen them used for $10k once or twice.
