I think you could be very happy with either speaker. Both are very nice. Another I highly recommend is the Linn Katan.
I have owned the 12L and the Audience 50. I didn't care for the occasional treble glare in the 50s but that may be resolved in the 52s. The Quads tweeter is very nice and detailed but not overly etched in my opinion. Bass is nice on both. The Quads had a dryer midrange to my ears, with the 50s being just a bit more forward. Both resolve well.
I ended up selling my Quads for Linn Katans which, to me, make the music come alive. Not by more bass or highs but by musical tone. Is hard to describe but if you get a chance you may want to try the Katan also. If you do, listen to the tune of the song, not just the sound of the drivers in comparison. I'm hooked.
Enjoy!
