Given the easy impedance (min. 6 Ohms, see graph) of your QLN Prestige 3 speakers, I would give the new and terrific NuPrime AMG-STA ($1695) a try, seriously. Compact and lightweight (8.8 lbs).
Input stages in class A. Output stages in class D.
Initially, I did not want class D amplifiers, not even to jam a door. I nevertheless had the opportunity to listen to the at home, and bought them in 30min. (with their AMG-PRA preamp, amazing too). This was for a 2nd system. But they are amazing.
Very nice-sounding, with a lot of transparency, image precision, and timbres (I listen to classical!). I was very, very surprised. Now, I think not all class D amplifiers sound that good. Moreover, you have to say "class D" with hyphens, as then did not pick up off-the-shelf class D modules (Hypex, etc). They wanted their amp to sound much better. They build their own circuit with very high switching frequency to reach the most "analog" possible sound.
2w130w. Switchable in mono mode (=> 2xAMG-STA gives you a pair of monoblocks for only $3390. It is this combination that amazed Christiaan Punter, excellent Dutch reviewer (see Hifi-advice review, hereafter).
The Absolute Sound "highly recommended" (review)

I really appreciate their weight when I have to move them around. They sound much, much better than my 80w, 40lbs Marantz PM-16 in that 2nd system. I have not yet compared them though to my YBA Classic + Aries Cerat Incito preamp sitting in my main system (in another town).
