i have a pair of the alon II's. a cousin to the dq10's ( they are pigs when it comes to power requirement- to say they like current is a understatment)
i would not go any less than 200 wpc with a high quality design.the aragon should do fine but alot will depend on how much you want to spend.
they can get buy on a quality 100 wpc but really they really open up and breath with 200 wpc. the sound is very effortless and organic.
here are some options:
muse 160 stereo mk II($600- $625 used) and add another( the muse has a very nice top end that is a good match for the dq10's)and that would put you at $1200-$1300 for 2 near state of the art amps.
or
2 muse stereo amps- $375 each or 2 pse studio IV stereo amps($325 each) - $ 700 - $750 for 2 stereo amps
or
4 pse studio v mono blocks - $500 - $600 pair - $1000 - $1100 for $5000 (retail) of very quality amps (this is the route i went). the pse's studio V monos are very hard to come by.
the lower price pse studio V and muse 100 are very good amps( $1k range new ) but lack the last bit of sonic refinment when compared to their more $$ counter parts. the muse 160 mk ii was a $2k amp and the pse studio V are a $2500 pair amps
you do have some choices - the speakers will sound very good if you have a tube pre in the system.
hope that helps,
mike
