I have the A12t and use them specifically on stage. I wouldn’t say they are technical, but I wouldn’t say that sound exactly like the U12t either. The A12t, for me, has more low end and a warmer top end with good treble extension. I play guitar, and feel like my guitar sounds like it should. Hope that helps!

Our trombone player uses the A series too and is happy. Maybe I can try them all out one day Thanks!
