DK sound can be tuned with input tubes and cabling, and there is substantial power, so I would be very surprised if this were not a nice match.
Maggies like lots of current. If the power rating (watts) of the DK doubles from 8 to 4 OHM this would suggest it would do well with Maggies in general.
I used to own 1.6s and drove them with a Plinius SA 100 MKIII amp that had 100 watts and it drove them much better than a Plinius 8200 integrated that had 175 watts because the SA 100 is a true class A design with lots of current.
I'm sure the DK will be a good match, but according to some the DK is NOT a true class A design. I doubt it, myself, because the amp runs pretty cool. How many 150 watt pure class A amp do you know that is barely warm to the touch? I know of none. DK is not forthcomming about their reasoning behind their class A claim.
I doubt that the DK is pure Class A as well. Their specs are very criptic (much like YBA/Audio Refinement). As with the YBA/Audio Refinement gear (as well as all other gear) I think that the DK should be auditioned at home with your speakers to know if it works well. The DK stuff catchs hell hear in the forums by... lets not call them pretentious... well-meaning audiophiles with deeper pockets and more deep-seated predjudices than most. However, my untrained ear found the DK integrated to be very enjoyable to listen to.
A got an e-mail from a guy with Maggie 1.6's a few months back. He wanted some advice on what to look and listen for on a pair of Apogee Duetta Signatures he had found used near his home.
A follow up e-mail stated that his amp was the DK integrated and that it drove his 1.6's with no problem...he also stated that the DK was working very well driving his new Apogees.
I have owned and driven both 1.6's and 3.6's with my DK amp. I found it was a very good match - lots of power to drive a very inefficient four ohm load. It offered equally good midrange plus better bass control than my Sonic Frontiers Power 2. I sold the SF after comparning it to the SF in my system. I'm now using the DK with a pair of diy line arrays. These speakers require an amplifer that has especially good bass control, and the DK excels in that regard.

I have used an Innersound ESL amp, that had an extra large power supply, and put out 1000 watts into 4 OHMs and they played extremely loud without damage. a drum solo on them was louder than if real drums were in my living room... no kidding.......
Do not worry about blowing Maggie 1.6 with clean power. I have heard the true ribbon tweeter on 3.6s can be blown rather easily though...
Actually, many people dont realize that it is the low powered amplifier that is most likely to blow your speakers since it can go into oscillation and also does not have the proper damping factor to protect the drivers. A high power, high damping factor design, with low distortion will protect your speakers.
