[please forgive my poor English]
I browsed through this thread, and noted a few interesting points. I'll quickly give some input, for what it's worth.
Alsyvox ? Terrific panels, but no-GO for you alas: you have only 30cm left behind the speakers.
Stenheim Reference Ultime Two ? Terrific speakers, but I strongly doubt they would fit given your 2,60 ceiling.
Moreover:
1. I am 70% sure you don't have the minimum volume required (large room, but also low ceiling). To be seriously checked (with the help of the manufacturer, if necessary).
2. back ported anyway => not recommended (you have only 30cm left behind the speakers!)
Horns? Your listening space is approx. 16m², you wrote. So I would not go horns as you probably listen midfield.
MBL? Great speakers for "ambiance" and casual listening, from anywhere else than the sweet spot. I love them. But I'm sure you wouldn't consider them as an upgrade vs the Stenheim Alumine 5SE. In a 135m² loft, MBL would be great: plenty of space to put them at 1/3 of the room's length and set the dining room behind the speakers. But in a 35m² room, with speakers located 30cm from the rear wall as you mentioned it, forget MBL.
Others? I am sure some very nice but less known speakers exist, and have been mentioned by experienced members. But it will be difficult for you to listen to
those speakers, not to speak about having demo'ed at home.
So,
IF you know that the Alumine Five works well in your room (which is an
invaluable given in this equation), THEN why not
- stick with that.
-
upgrade your room acoustics !!!! Call an expert. I think
he will come in your room.
- Optionally, why not upgrade the Alumine 5 SE to Alumine Five
SX ? (
@Perfect sense Audio made this suggestion too)
- At last, if you have enough space and if you have nothing against tubes electronics, why not try Aries Cerat (AC) electronics?
- no, there are definitely not "rosy view" and sloppy tube gear
- not all AC gear will fit the Alumine 5. My feeling is that their unique TriodeFET technology can be a good bet regarding the power amplifier (it can drive loads down to 2 Ohms). The model to try also depends on the average SPL you want to reach. Get advice; there is an AC dealer in Israel.
- if you have attended live un-amplified concerts in very good concert halls, I think a Stenheim & AC match will be strikingly reminiscent of "the real thing"
- I heard the Stenheim Alumine Two (non-SE version) powered by a full (big) AC system, in a dedicated room with SMT diffusers: one of the very best listening session of my life, as simple as that (on chamber music and voice, as the bass is of course limited with that 2-ways monitor). I attend 30 to 40 concerts/year.
It also depends on your reference, that we do not know: is it concert halls, live music? Then the reference is that thing called "reality".
Or is it pop & synthetic music? Rock? Audiophile recordings? Jazz? Miscellaneous?
Anyway,
Absent an in home audition, one hell of an expensive crap shoot.

Good luck.
