Speaker upgrade

That size room, I would give the Heresy IV a good listen. Angled base projecting drivers at seated ear height, and alters angle of reflection off floor and ceiling. Toe in to avoid side wall reflections.

Square rooms can be challenging, I would look to make the rear wall behind you non-reflective, 

Hello all, I truly appreciate all the feedback regarding my post. 

My absolute top budget is $6k, without selling my plasma and a vital organ.. I am intrigued by the Spatial, spent some of my evening reading up on them as well as the NSMT's. I would prefer made in the US, our friends to the north, or the UK. That is not to say that I am ethnocentric. I have bought and sold plenty of gear from China, Japan and elsewhere. I mean have you all seen the Line Magnetic Western Electric recreation horn system? A bit dear for my billfold, but a man can dream right? Also on my bucket list, Luxman.. I have owned speakers from TDL, Mission, NHT, EV, Rogers, Kilpsch, Morrison, Design Acoustics (really?) and my current pair of Tyler's which i do love. I refurbished a horn and low end cab pulled from an old theater, 1940's International Projector Co. (the drivers themselves are Jensen), it sure sounds fun in my second garage. (it spent one month in the house, at least the spouse gave it a chance)

It may be elusive what I'm attempting to get across. The sweetness, soundstage and warmth of the Tyler's, the accuracy of the brit's and the dynamics/raise the arm hair of the Klipsch. I do not wish to offend anyone, we all have our own tastes, we all find what we enjoy in a speaker or system. I feel I'm as close as I've ever been. 

I am a man in mid fifties, and never thought I'd hear myself utter, "remember the golden days", but here I am. I miss picking up my best friend and going to audio stores near and far. I miss working in a proper hifi shop, the best one here in NE Ohio, "The Speaker Shop". Miss being able to sit and audition whatever it was seeking.   

I bought a new pair of speakers earlier this year and demo'd all the speakers you mention. I bought Charney Companions because they had more of the strong "right there in the room" imagery that I suspect you're looking for judging by the list of speakers you are considering.

I have a hard time believing my Rockport Avior ii speakers have any cheap parts although I didn’t delve that deep into it. The outstanding reviews and comments on here and WBF were enough for me. 

@doyle3433, since you mentioned listening "mostly to Jazz", I would recommend adding Revel to your list. Frankly, however, the Revel line in your budget range will do justice to just about every genre of music, as will your MoFi Ultradeck+M. Full disclosure: I own a pair of Revel and your MoFi deck, powered by a McIntosh amplifier.

This would be a stretch for your budget, if your intention is to buy new, but I would REALLY, REALLY recommend you do some serious seat-time with a pair of Aerial Acoustics 6T, even if you have to do some significant travelling to spend time with them in, of course, a scheduled and carefully orchestrated, critical listening session. I'm not terribly familiar with your amplification source, however. The Aerial require a lot of juice. So, make certain your amp can generate the kind of current (not watts) the Aerial need to sign like the angels.
