I have to admit that I didn't have had the chance to listen to Stenheim Alumine Three, but I doubt that they are building THE best speakers.
After spending 3 days at the High-End show in Munich, in 2019...I left most impressed by the sound reproduced by MBL (german manufacturer) 101 Xtreme top of their line speakers/audio system.
I also got the chance to listen to a pair of German Physiks (as the name directly indicates, is another german manufacturer of high-end loudspeakers) Carbon Mk IV, and I just can't imagine how fantastic can be top of their line, The Gaudi Mk II.
If some of us can't afford to buy and enjoy this level of musicality and emotional impact on our homes, I wish at least that the rest of all of us, audiophiles, music and quality aficionados, to get at least the chance to audition these true marvels of audio engineering.
