My impression (based unfortunately on listening in very different rooms) is that the YG Sonja 2 has more energy at the frequency extremes and is the "flatter" of the two, while the Magico M3 is "warmer". As to which is the better match for your Ayre amps (very nice amps by the way), I don’t know but imo a "tie" goes to the Magico for its higher voltage sensitivity.
What I’d also look at is speaker/room compatibility. You mentioned that your room is acoustically treated, which can mean different things. If your room was optimized for the KEF Blades, I’m inclined to suspect it might be a bit overdamped for the Magicos and their more subdued top octave.
Best of luck with your quest!
