I had DQ-10s while at University, and for a couple years after. I installed a nice crossover and driver modification which was popular in its day. As a college kid, I bought speakers first and slowly assembled the rest of the system. First, I used my Pioneer 45W receiver, and they sounded remarkably OK. Then I borrowed my buddy's Apt Holman amp/preamp, and I heard a nice improvement, with more separation and cleaner sonics. Then I bought and later modified a Hafler 500W amp, and it was significantly better than the Apt Holman. Not sure, but I think I was running a Counterpoint preamp by that time, just before going to Audio Research SP-8. Just trying to give you some feeling for where the AH sits, but it was between the Pioneer and the modified Hafler. Simply put, the DQ-10 requires juice. Do not skimp. My buddy still uses his Threshold 400A with good results. A CODA high-current amp would do well too. You need high current, not just high watts. The right amp will pay dividends, as you will see. Find the amp that is designed to push that kind of load, like the two mentioned above. Go Man Go!!
