$35000 to $40,000. speakers what would you buy and why?

I went from Martin Logan Electrostats with one sub to conventional Tower speakers with no subs, so, I was in a similar situation...   Speakers are a very personal choice, but, here are some things I noticed:

1.  Conventional speakers may sound a little bright from your current panels because of the focused tweeter.  This is not necessarily bad, but, based more on the architecture change you are making.  Give it a chance before dismissing speakers that may sound initially bright.  Toe in and positioning makes a big difference with "brightness" with conventional speakers. 

2.  For Bass, to make sure you will not want subs,  look for tower speakers with 8 inch plus woofers and a 19 to 20 hz +- 3db rating or lower, ie. consider 8.5 inch and 10 inch woofers..  12 inch can also be great, but, not very common.

3.  Speakers from a specific manufacturer tend to follow a similar formula.  Read up on what that formula is, make sure it is your cup of tea,  and try to listen to at least one of the speakers that the manufacturer makes.  Even if it is not the model you are considering for purchase, it will give you a taste of their sound philosophy. 

4.  Opposite to what you currently have, conventional speakers move a lot of air.  This gives you that "chunk" and "push" that you are currently missing.  Look for that in the speakers you consider...  It is one of the reasons you are moving away from your panels. 

5.  If you are near a big city, for that kind of money, you can punch higher with used speakers on Audiogon and Audiomart.  Of course, they need to be local, so, you can go listen to them.  This is how I did it, and I am very satisfied.

Personally, after many years with Electrostats and a subwoofer, I am glad I moved to conventional tower speakers....  Even though I miss the wide dispersion of the panels, proper positioning of conventional towers with the massive movement of air has left me more pleased with my sound.  

To add to my post above, without subwoofers, Bass satisfaction can sometimes be the most challenging while selecting a Tower Speaker.  So, you could look for a manufacturer that satisfies your bass taste first, then, move up and down their model line to see if you can get the midrange, tweeter detailed articulation you are looking for.  Personally, I selected used Wilsons, but, there are many compariable brands you can try this process on. 

I would definitely get the Vivid Audio Giya G4Cu.  Having lived with the previous version (G4s2), there is nothing like these speakers. Perfectly neutral, engaging and dynamic.  They tell you things about the performance you didn't know existed yet are musically luscious and captivating.  And the 3-dimensionality is the best I've ever experienced.  It's an easy choice for me.

I've heard the Franco Serblin Ktema's that are just plain MUSICAL. Seek them out for a listen.

You have an impressive list under consideration.  However, I do not see some models coming in at your budget preowned, even if you can find them available.  For example the M-Project and Alumine are special order listing at around $140k depending on finish.  At 40% to 50% retail preowned, that’s $56k to $70k, above your $40k budget limit.  The Homage may come in within budget.  I am a Vivid fan, and the Giya G2 will also come in budget, but you have to like the eccentric aesthetic, which I do.  
 

You have impressive, end game electronics and your current speakers are not in the same sound quality class.  From your choice of electronics I would assume you prefer a warmer, rounder, emotional presentation over clarity, transient speed, and detail.  You need to choose a direction.  Do you want a speaker that will be synergistic with your electronics that will reinforce the warmth and romance of your electronics or that will bring an added degree of clarity, and increased leading edge transient edge? To my ears, and you need to audition yourself, if the former is sought, go with Sonus Farber, Rockport, or Magico M3.  If the latter is sought, go with the Magico M Project, Stenheim, or Vivid (the Vivid would be the most three dimensional of the list but focuses on clarity, transient speed, and dynamics). So you can understand my perspective, I error on the side of clarity, detail, and transient speed.  Therefore, I would go with Vivid or Stenheim.  If your prefer the warmer side of reality, with your electronics I would go with Rockport as the best choice.  Please audition for your ears may be different from mine.
