Definitley the DQ-10's. They have stood the test of time and then some. The user "Hemjr2" made a statement in his previous thread: "my dq-10's sounded great the day i bought them and i'm sure they will sound just as good tomorrow. i would like to hear what a pair of dq-2003's would sound like. take the exact same design and use the best of today's technology, super long throw woofer using the lastest composite materials, kevlar mid-range drivers, silk dome tweeter, replace the peizo super tweeter with a ribbon, top of the line wiring and electronics in the crossover, super robust construction in the cabinetry, etc"
No need to guess if you are willing to spend the money to have them upgraded. I own a pair with nearly all of the aforementioned "mods", rebuilt XO, Ribbon tweeter, etc...
and they sound like angels. I use them with a pair of Velodyne 12" powered subs, rolled off perfectly with the DQ-10's, I obviuosly have NO bass problems. The DQ-10 is the most discerning speaker "for the money" (crucial point) that you will find IMHO. I have no problem driving them to stratospheric levels with my Krell amp, and they suck it up and just ask for more...I have heard Martin logans, Theils, etc... but they just don't impress me for what they are being sold for, the "bang-buck" just isn't there, which only serves to make them a disappointment. They are expensive, and really don't bring much more to the table (sonically) than speakers costing thousands less...The DQ-10 stands alone in my book...30 years and still going strong..
