The DQ10's require an amp that can deliver good muscle. A high current 100 watt amp should drive them well. The 200 watt rating means that a flat response (with not added bass or treble) your speakers will handle approxiamately 200 watts. It doesn't mean you have to have 200 watts to use them. I personally think a very good quality high current integrated amp or power amp will do justice to them. Because you are new to this I would suggest solid state over tubes in this case. A very good combination could be a good tube preamp with phono if you need it if not a tube line stage and a Hafler DH 500. Thats 250 watts of clean power that sounds pretty good. It depends on what your budget is. There are many amps and integrated amps in this forum that will go a great job.
Subs: I think it helps them alot if you do it right. Meaning if you have a properly designed crossover that rolls the response of you main speakers off and then the sub blends in to fill in the bottom end, that will free up the DQ10's to play that critical mid band and top end and the subs will take over and produce the bottom end. This will give you a much better sound presentation. You also have to set them up away from the rear wall too. The DQ10's have some bi-polar dispersion. Meaning the tweeter and midrange sends information forward and towards the rear wall in real time. When I owned mine in the mid 80's we didn't have many choices of powered subs. I like the Hsu subs. I'm using Dali Suite 1.2 12" acoustic suspension subs in my listening room. Dalhquist made subs back in the day and they were Acoustic suspension. The crossover made to drive them was wonderful. If you are using it in just a 2 channel system you have many options. In a Home Theater you will most like the Hsu's also. The Hsu's are a great value and very good sonics too. There are many more subs I like but it depends on the price you want to pay.
With all that said if you like the sound of the DQ10 and what it does for you Keep It Simple and you will get a
big surprise in the end.
