Considering moving on from B&W...

I completely understand your interest. I highly recommend a trip. Plan a weekend in Atlanta or a city with some good high end audio stores. Make it a fun weekend. Make appointments with one or more audio stores. Ones with Sonus Faber speakers, Wilson, and Magico as a minimum.

This is a worthwhile investment. You want to fall in love with the sound. For me after decades chasing planar speakers it was Sonus Faber. You should also listen to The others I mentioned… although I am pretty sure this is absolutely not the direction you want to go.

For me Sonus Faber and Audio Research offered great detail and incredible musicality… I get captured buy the musicality of my system every day… I have to drag myself away from my system each day… even though I listen three and a half hours a day.

Go see OCD Mikey he is in Atlanta. That’s a joke.

As a former Sonus faber owner, I would go listen to QLN, Sonner, and Rosso Fiorentino.

I am very smitten with Sonner.

If you like B&Ws and you have the 802s you will likely not like the Magico A3. 
I was in a process of moving on from the Martin Logan Montis that I had for several years and went to audition Magico A3 and they did nothing for me. Dark, overemphasized bass, slow and not engaging. There was a sense of having a thick blanket over the speakers. Build quality is top notch but I thought I heard some of the artifacts of the aluminum cabinet. A5s are supposed to be better but at a much higher price. 
 

I owned B&W N803 years ago and would take them over the Magico A3 any day. I would consider Focal, Sonus Faber and Wilson Audio. 
Just my opinion. Definitely audition prior to buying anything if you can. 

Although I agree, if you like B&W Magico may not work for you, I’m afraid I have to disagree with audphile1 observation. I own the A3, and they are nothing like what he described. Perhaps they were not set up correctly, or he is used to lesser neutrality. If you look at many of the latest B&W, their freq response is extremely tailored. If that is what you are after, the Magico may sound boring. Many audiophiles consider hyped trebles as detailed and exciting. To my ears, they are simply unnatural and fatiguing.

Magico are really fast and take on the character of the equipment you feed them with. So, at least to me, you have to have really good equipment or you are going to hear any shortfalls.
