Speaker upgrade


I would like to hear thoughts on upgrading my speakers. I am very happy with my current system, but am thinking of upgrading the speakers. Not made up my mind yet, but very close. I have changed my gears recently and deciding whether to keep my current speakers or try different.
I currently have Aerial acoustics 7T, with 2 REL S5/SHOs. Aerial acoustics 7T are one hell of a speaker, and I never thought I will change them: they are very neutral and transparent, which plays exactly what you feed them. I still think they are excellent and In fact, on many forums, I have constantly bragged about them and still do, for good reasons. But I guess, time has come to change. Looking for speakers with better resolution, big soundstage, organic and sweet mids. If I can get more of everything my 7T does, it will be a jackpot. Budget is < 35K (used OK).
I have thought of Magico S5 MK2, Vimberg Tonda, Marten Mingus, Rockport Avior II. Others include Von Shweikert VR55 and Vivid Audio Giya G1. Hard to audition all, but have heard S5 Mk2 and Rockport Avior II which are close top.
My other systems include, AF strumento no. 4 mk2 amps, VAC renaissance mk V pre-amp fed by Luxman D-10x (DAC/SACD player) and Antipodes CX/S30 (server/streamer). I use roon mostly and listen vocals, Jazz, classical, Indie Rock, contemporary instrumental and the likes. Room size is 17 x 14 and height is 10 feet. I have already done all room acoustics. Cables are Silversmith Fideliums (never going to change that) and Shunyata anaconda/python, TQ black diamond and AQ Hurricane.

@audiokinesis You have very good understanding on room acoustics. Very few people have that, including me. Will certainly be in touch with you when I have to do some more changes, which will be done after my speaker purchase.
@abd1 I have heard some reviews on Nenuphar mini and 10 inch speakers. I heard them on videos too and they sounded very musical and clean. I am not sure, I might go for them. They are best with tube amps. 
@larryi Vandys especially model 7 are phenomenal as per many people and reviews. I may consider putting them on list, if I can find a dealer near me. 
@danvignau That will be ideal. I wish I could listen to them extensively but so many factors including the set up, audio gears behind them and the room where I hear. 
Looks like Joseph audio gets many votes, for good reason. This speaker has advantage of being an underdog among big players and hence a lot of sympathy. I can sense that and I also want to promote those kind of brands. But besides that, are there anybody here who have owned them. Will be good to hear from them too. It is easy to recommend all these speakers (some of them are so new to me), but consider this: "if it is my money, will I buy this". Throwing all the speakers at me when I am trying to narrow down makes it a long discussion without results. Meanwhile, I am going to find dealers to listen to Vimberg Tonda, Vonschweikert vr-55, Vandy 7, JA pearls. Will again listen to Magico S5MK2, and Avior II to make final decision.
I bought my last pair of speakers 10 years ago, Soundlab 945's, hot-rod, toroidal, bass focus. EVERY change made upstream is revealed. The  MOST sound investment I have ever made, Period !!
