[please forgive my poor English]
I totally agree (of course, not referring to show conditions either).
Though TBH I only know the small two ways
Alumine Two, that I first heard in a show, with my discs (disappointed, because the setup had some 'idiosyncrasies'; but I could glimpse a huge potential). Later on, I heard them on my discs again, in a dedicated room (SMT diffusors, Helmoltz resonators into the walls, Aries Cerat electronics): the result was nothing short but stellar (for the size and price) in terms of immediacy, lifelikeness, "suspension of disbelief" regarding the midrange, and (subjective) linearity. Slightly lean bass though*.
I was then tempted to call them "little horn-like cone speakers for people living in a flat".
* therefore their new floorstander I guess, the Alumine Two.Five
(it's reassuring to see a horn-lover like you liking those cone-speakers ;-)
Alas, Stenheim is not distributed in my country, so no way to listen to the bigger, floorstander models (Alumine Two.Five, Alumine Three, not to speak about the Reference Two you mentioned).
I seems so, indeed.
My feeling is that, being
extremely revealing, it's ways easier to get something overly analytical through them than getting beautiful, natural music. Maybe a bit like Cessaro, about which you once wrote (maybe in PM) that you felt a huge potential, but had not been convinced by any demo yet. Apparently, the revelation happened with the little Cessaro this year, that you seemed to enjoy very much. I would not be surpised at all if it's a bit the same story with Stenheim (at least, it is what frequently attending live concerts suggests me when I faced the Alumine Two's twice, in various conditions).
