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.

@bpoletti I would like to thank you for your suggestion of placing the artificial ficus tress behind speakers. I placed few artificial palm trees behind my speakers, and yes they made huge improvement in sound. They are very good sound diffusers and made huge change in sound positively. I think, this is one of the best bang for buck on SQ other than my Fidelium speaker cables. I am planning to get some artifact ficus trees to keep between the speakers too. Once I get my new speakers and all set up, I am going post more, including pictures on Agon. 
@romney80....  

Thanks for the kinds words. 

Artificial ficus trees are not my original idea.  But they are certainly effective in reducing room problems and one of the best bangs for the buck in acoustic room tuning.  
To expand on the use of artificial ficus trees....  They are diffusers,  The leaves deflect sound rather than keeping a coherent soundwave bouncing off the walls.  It breaks up and helps absorb the sound waves. 

The ficus trees are also have much more WAF appeal than the typical room treatment.  They are available from @home for a fraction of the cost of typical room treatments.
Update: I finally got my monitor audio PL500II and the speakers are just wow, even new, right out of box. Amazing speakers. The mids are smooth and magical with addictive sound. Very musical with big soundstage (really big). Worked around with speaker placement and they got three dimensional. Oh my, they are one hell of a speaker for the money. You know when you hear, if it is real deal, and this one is, beyond my expectations. I am so sorry that monitor audio does not get much attention especially this world class speaker. I am a happy camper. Aerial acoustics 7T is a damn good speaker, and I was very skeptical if my new purchase will be better, but MA PL500II is winner for me. I am glad I made this purchase. 
romney80   I just saw you r response to my statement.  I did not mean to state my opinion as an absolute guide to follow.  To be more clear, since so many places no longer have actual stereo stores, I believe we must take others' listening opinions with the proverbial grain of salt, bu ttj=hen seek out a store or home demonstration, when possible.. An extreme example of where this feeling comes from can be found in the rants of how wonderful  everyone says his system is on the Audio Review site.  I am guilty of such.  We all are to some degree.  I did not mean to suggest that we ignore the opinions on Audiogon, especially since this community does have a lot of experience with many different products; however, we still need to be aware that many of us have not been exposed to a great number of products, and that we tend to like what we have.  As James Bonjiorno of Great American Sound (Ampzilla) warned us:  If we take six people with their own LP's and CD's to each other's homes, each system will sound best with the media of the owner of the system.  I like to add:  We buy systems to sound best on what we listen to, and vice versa.  We are all biased, and must remember that.  Good Luck with your search.  Cheers
