Considering moving on from B&W...

Magico are incredibly fast and accurate speakers… does not at all sound like the right direction for you. Magico require extremely good and musical input or you get analytical… and the shortcomings of your electronics reproduced with great accuracy.

I have recently listened to the A3 for several hours. The top of the line Luxman amp. Musical they were not. Sounded pretty good… but not real musical.

I have had very accurate systems for decades… but somewhat missing the musicality… you can see my current systems under my user ID. They are incredibly musical… but with all the detail (a long story). To me musicality is critical (rhythm and pace with midrange bloom).

So, to me the most musical speakers are Sonus Faber, high detailed and musical components Audio Research… then realy musical components Conrad Johnson and VAC… Cary. Notice they are all tubed…

B&W and McIntosh have a very distinctive sound… great for rock… and some other heavy genres. But real musical and detailed systems you must look elsewhere.

It might have been helpful to mention what's in front of them:

:Surround Proessor : AVM90

Preamp: McIntosh C2700 Tube

MC452

MC207

MC205

SACD: McIntosh MCD301

blu ray: Oppo -203
 

I am not sure Magico A3 is going to be a step in the right direction for you.  Magico’s are great but similar.

if you are looking for the same image with a softer, more musical presentation Wilson Benesch, Joseph Audio, Vandersteen, Verity are all brands I would look at.  These are all “cone and done” speakers and present a similar image.  
 

Ribbons, AMTs, electrostats, planars all deliver a different, more immersive experience.  

At Axpona 2022 the magico I’ve heard are unbelievably good and musical, they are hook will expensive gear and synergistic cables.Magico Speakers with the right set up and components they will sound musically amazing.Your gear there is a chance they will match the magico.

Jof stick with Magico   Audition if you can .they are world class speakers.
