Who has heard and can comment on any of these brands??

I've heard of but have never actually heard or demoed Stenheim speakers. The last time I was seriously shopping for a pair of towers for my two-channel system upgrade, I spent serious seat-time over several months with approximately 15 or 18 different contenders in serious, orchestrated and scheduled critical listening mode. A pair of Aerial Acoustics 6T were one pair I spent time with that absolutely blew my socks off! Unfortunately, my amp doesn't generate the kind of current these fine speakers deserve to do them true justice. For those of you who may be reading this, have the right kind of amp to do these speakers justice and around seven grand to spend on an upgrade, I can't encourage you enough to do what you have to do to audition these speakers! These Aerial 6T I heard were a pair of trade-ins. After the audition, I asked the salesperson what the people who had owned these outstanding speakers traded them in for. He pointed to a pair of Stenheim Alumine 3. If I had 30 grand to spend on a pair of speakers and the type of playmates they deserve, I would love to hear these things for myself.

I heard a pair of Stenheims at AZPONA this past spring (2022) and found them to be one of my favorite rooms at the show, just behind the Magico M6 room.  The Stenheims were in a larger room, and I can't remember the model number, but they were wonderful sounding.  My show companions were in agreement with me.  Maybe this helps........

I have Coherent 10's.  They are in my virtual system posted here.  I'm not familiar with the other brands mentioned by the OP.  Coherents will be in the high efficiency camp.  Very easy to drive, outstanding clarity in the midrange, great imaging, very revealing of amps.  I've heard more extended bass and more detailed bass elsewhere but the good stuff more than makes up for it and I don't feel like bass is lacking at all. 

Audio Physics, Stenheim.

About the fabulous Stenheims, I posted this on Audiogon, so useless to repeat myself:

Go listen! They are really astounding.

Whilst seeking to replace my Audio Physic Yara 2's I took them to a friendly hifi store to compare them to a range of speakers most noticeably Monitor Audio's. I tried them in the main listening room against maybe 12 speakers. The Yara's sounded, to me, by far better. We went to another room listening to some others we may yet consider.  Whilst there another salesman came in and asked the owner how much the new speakers were, a customer and his wife just loved them. I did upgrade the AP Yara 2's, for another pair of AP's, the Sitara 25's. Perfect for my small dedicated music room.
