Replacement for 802 D3s

It's not the speakers it's your front end. I auditioned Macs and Blades with the 802d3 and 800d3. Far too weak, I would not recommend Macs and the blades were far inferior too. I use Bryston (7b3 and 28bsst2) and they provide very strong results

i.e. The 800d3 is an ideal uplift to the 802d3. It seems to be a standard upgrade - followed by many

Magico A3. I will have a longer listening session next week!

Have you looked at Wison Benesch?  There are not a ton of dealers out there to help you with auditions but they are brilliant speakers and will be a bit more natural sounding than B&W.  I would look at the A.C.T. One.  

Vivid Audio is not necessarily going to be significantly less bright, (Laurence Dickey is ex B&W and designed the Matrix and Nautilus lines) but these are incredible sounding.  Aesthetically, you either love them or hate them but few critique the sound.  A Giya G3 should deliver very room filling sound.  

Both of these are some of the best engineered speakers in the world and would be first choices for me.  I am in the process of becoming a dealer for both brands and could blather on for pages for why both.  Cabinet materials, driver design, etc... all make them fabulous.

Regarding other options:

Rockport makes insanely good speakers and again, are a bit more natural sounding.  Wonderful engineering and you can't go wrong with the.

Vimberg or Tidal - they take a while to get but are awesome speakers.  

YG and Magico - Aluminum cabinet and both are worth a listen.  YG has an awesome upgrade path.  

The 802s are sooo young.  Give them a few more months to breakin and mellow out.    Add some absorption panels to room and a carpet. Set crossovers to 40.  Get a sub for less than 40.
