Point of clarification: are you referring to the old 2C, or to one of the newer, updated models: 2Ci or 2Ce? If you are referring to the original 2C, your impression that the DQ-10's sound better may be true. The original 2C was superceded by the 2Ci in the mid-to-late 1980's, and there have been a number of improvements since then.

Curious to hear opinions on these speakers.
