Speaker upgrade around 100k retail

ebm seems to have one major agenda; keep the hype going in regard to the products he owns. It appears he wants to protect resale value of the products he owns. He relentlessly hypes them - and gets angry when he has to take a loss on a sale of one of them.

Oh, yes, and he spends plenty of time mocking, dismissing others, which contributes nothing of value to the community. I wish he would cease that activity, which is neither polite, nor desired. 

Well, based on the updated info from OP, I recommend that if you "love" your speakers, you go up the line to the more prodigious model. Unheard, moving to another brand would be a complete gamble. It could pay off handsomely, but there is less risk of major disappointment when you adore the sound but want more. 

There most definitely would be discernible differences between them. But, whether you would enjoy the alternative set of characteristics is anyone's guess. You may have to start over again with electronics and cabling to obtain satisfaction. It's a safer bet to move up models in a specific brand. No one here can tell you blindly which would be preferable for you, so don't worry too much about how insistent some are about "the best" speakers. They're not the best unless you build the best system with them - that goes for all of them.  :)

I had a similar experinece working up the line of Legacy Audio speakers. A person gets comfortable with, enjoys the pleasures of a certain model, but wonders what else there is to hear. If you are simply itchy, versus displeased, then I think a move upward in the same brand is as close to a sure thing as you will find.  Enjoy the hunt!  

These are all excellent efforts and the companies that build them are fanatical about quality. I have a friend who owns the Stella Utopia EM, and they are indeed superb. I think the ability to tune the speaker via crossover adjustments is a nice benefit. That also would be the case in the recommendation below. 

I cannot speak definitely as I have not owned or reviewed any of the selections, but often at shows Magico has seemed a tougher result, a bit more sterile than I prefer. You may also wish to consider the largest of the Sonus Faber, which I enjoyed hearing. I hasten to say that I believe I could build wonderful systems with Magico speakers. 

The Legacy Audio Valor Speaker System has a rather unique sonic signature, as I discuss in my review for Dagogo.com, and if you wish to chat about it, feel free to send message. I believe it would compare well to these others. As well, Legacy Audio is often willing to do custom orders that allow special configurations, i.e. internal, external amplification. This individual worked with Legacy to customize their Valor setup.

Regarding "the bug," If you are continuously itchy to hear something new, perhaps you are like me and enjoy variety as a driver for system building. I suggest, then, that you consider the possibility of keeping your current speakers and adding one of a different genre. Perhaps something like the Kingsound King III electrostatic that I reviewed would bring a world of enjoyment as a trip to a different destination - panel world. The equivalent of my speakers is the Kingsound KS-18. You could even go full bore with the KS-31. Magnepan's 30.1 would be an alternative. If you wanted to dip your toes into the quasi-line source pool you could consider the Legacy Whisper (I wrote several articles about iterations of that speaker). 

You could go several directions; Open Baffle, Omni, Panel, Line Source, Horn Hybrid - they all have enchanting characteristics when set up well, and none of them can do precisely what the others do. They all do things that no traditional dynamic speaker can do. 

I find nothing quite so gratifying in all of audio as having variety versus chasing The One speaker that theoretically does it all. Doesn't exist.  :)
