I know this is a bit of an old thread, but I just heard the Magico A3s yesterday. Woah!
After selling my previous system: Wilson Sasha 1, with ARC Ref separates, I was ready to be disappointed by the A3s driven by ML 585.
Well, I was wrong. I was bowled over. They are now more than $10k, but to my ears they beat the following systems (for what I'm looking for)
Wilson - Sophia 3, Sasha 1 (don't best the Alexia 1s)
Focal - Scala v1, Sopra 2, Sopra 3 (I A/Bd the Sopra 3 in the same room same electronics - not even close).
The only system that I've had that I think this did not beat was Alexia 1s, ARC Ref75SE+5SE, w Transparent Ultra gen 5 loom. Lumin A1 was source, same as when I listed to the A3s.
I will be buying these.
Smooooooooth and extended top end, very well integrated between mid and tweeter. Could be a bit of a lul/suck in the upper bass (but could've been the room)
Refined and cohesive sound.
Non-fatigue; the tweeter (unlike the Focal) does not bring any attn to itself.
BASS... These were in a 20x24-x10 room. And, they were about 6 feet into the room. I was still wondering where the subs where. Not bloated bass or 'airy' (like Sopra 3) bass, but authoritative, solid, foundational bass.
Staging, imaging and focus were all very good. I could easily ear the difference between DACS (Esocteric, internal 585s, Lumin A1 and S1). Depth, focus, all there.
Transparency, with the 585 from Mark Levinson, was spot on - ARC Reference transparency.
I'll be getting these, maybe today :)
If you like Wilson and you like Focal, but neither are quite spot on, try these!
