It depends on a number of factors and I wouldnt say it is clear cut. The DB1's have the ability to sing just as much as the Menuets and electronics/music/room size all change the outcome. I personally favour the Dali's although the popularity of PMC ensures we sell more DB1's.
Yes, I found them a little lightweight in the bottom end compared to the DB1s and emasculated the Primare combo somewhat to my mind. But this was in a hotel room and based on memory after all. And it was by no means the most disappointing setup, some with much higher prices
