Having owned the DQ 10s ( and mind you, I had them phase arrayed and replaced with microfarrit capacitors) I'm wondering why, in this day (other than for the looks) you'd consider these babies. Granted they have one of the most satisfying midranges going, but that is it. Top end is very weak as is the bottom end. And, they need oodles of power. just my fwiw. I never gave the DQ 20s a serious listen, but they, certainly, look better than the DQs. To me, at least. peace,warren
