Replacement for 802 D3s

I have heard the 803d3 on mc601s and it was bright to me. Great demo but not a purchase for me (I have owned B&Ws in the past). 
I would look at the Sonus Faber the Largest Olympica Nova (5?) would actually be a little cheaper and a better speaker based on my demo of the Nova 3 and 803d3 demo (same shop different rooms gear....) The Serafino would be right in the price range and might be better. I have never heard it. 
The new Sonus Faber sound is neutral to me. Not rolled off at all with a little bloom in the upper bass. 
I don’t think you need the Sasha DAW unless you want the adjustable head. The Yvette would do the trick and save a lot of money.

for what it is worth I have heard the 802D2 803d3 (bright, needed played loud to come alive), Kef blade (meh), Reference 3 (boring no dynamics), Revel Salons ultima 2 (lean for your room and buttoned down) and most of the wilson line. I personally would choose the yvettes as the best of the group and the sweet spot for the money in Wilson’s line. 

Joseph Audio Pearl 20/20 could be another great option to consider.

Not in the least surprised by your reaction to B&W.  Trust us, even if you like the Paradigm at the store, they'll be exiting your house faster than the B&W.

Good alternatives: Harbeth and Vienna Acoustics.  Seek out the Liszt or the Music if you can swing it.

Otherwise as stated, Sonus Faber, Joseph, Vandersteen.

I bought the persona 7f 5 months ago and drive them with a hegel h360. I think what impressed me most is that the bass is as transparent and fast as the rest of the system. Your list looks like a win, win, win. The Wilson being the biggest pita to dial in, but always sound amazing at shows. Have fun.

I’d highly suggest only looking at speakers with a cloth dome tweeter. Having auditioned a ton of speakers over the years, I’ve generally found myself much more drawn to them and tend to find metal dome tweeters too bright and harsh for my tastes. That includes every pair of B&W’s I’ve heard over the years, which I find to be particularly bombastic.

I ended up with Egglestonworks speakers which, to my ear, are incredibly well-balanced, image wonderfully, and are designed to be non-fatiguing for use by mastering engineers.

I’ve heard a few Revel and Harbeth speakers from your list; I don’t think the Revels will be what you’re looking for but you might like the Harbeths. I’d describe them as a bit of a magic trick - the ones I heard (can’t remember which, maybe the HL5s?) sounded absolutely huge compared to their tiny size and completely disappeared. I didn’t find them as musically engaging as the Egglestonworks that I directly compared them to though.
