I have owned both, and unless you want to do extensive modification to the DQ10's, the DQ20 is much better at everything. The DQ20i (which has bi-amp capability) is even better than the DQ20 - until recently I had a pair of each. The difference is subtle, but I find the DQ20i mids to have a bit more detail, or texture.
Both are truly great speakers for the money - see my other recent posts here regarding DQ-20's.
Also note that if the woofer surrounds are original, they will need replacement in the near future - especially if you work them hard. No big deal (you can do it yourself in about 4 hours if you are reasonably skillful) but be aware of that.
