I got Q3 in my living room and I am impressed. The tonal balance is rather different from what I heard at my dealer with Soulution. Q3 replaces Usher Be-20 DMD in my room. Lamm M2.2 certainly has not problem driving it in 8 ohms tab mode. I have not tried 4 ohms tab yet but figure that Q3 may benefit from a bit more power.
Surprisingly, Usher Be-20 diamond tweeter appears to be a bit more extended than Q3 at the moment (with the same Lamm amplifiers). However, these Q3s only have about 200 hours of music playing so far. I understand that it will need about 500 hours to break in.
I understand that some people complain that Magico is not suitable for rock and bass heavy music. In a way, it is true that Q3 does not have the volume or with weight of Be-20. But its bass is almost as deep, faster, more precise, and much better detail. I could hear the note in each instrument much clearer. Be-20 in my room has rather big bump from 50Hz all the way down to 20 Hz and some people may prefer its punchiness and slam over Magico, I suppose. But listening to large scale orchestral work, I find double bass, tympani etc on Q3 to have more natural and realistic balance in comparison to what I hear in concert hall than Be-20 and other great port speakers that have bigger bass slam than Q3.
I have been debating about upgrading Be-20 to V3 for a couple of years, feeling that it was not quite worth the upgrade even though there are many things that I really like about V3. Q3 however is a clear and worthwhile upgrade, at least to my ears, anyhow.
