"The Stenheim Five SE is not just a great speaker; it is one of high-end audio’s greatest speakers. Its ability to generate truly deep, linear, powerful bass, unusually rich and lifelike tone color, near-visible three-dimensional images, and astounding detail and dynamics from such a modest enclosure is not just a surprise; it is one for the ages."

-The Absolute Sound

"Stenheim showed its €50k Alumine Five four-driver three-way with Audio Consulting turntable, preamp, phono amp, and amp, Nagra digital, and Brandt cable from Geneva. This was quite a remarkable setup as I heard things through it that I hadn't heard as clearly on anything else, such as Paul's fingering of Sebastian (his twelve-string casket-style guitar) on my PP&M LP. A Best of Show contender, for sure."

"If you need a compact speaker that allows your music to breathe, that’s big on expression, big on intimacy and communication but isn’t phased by big or loud, then the Alumine 2 could be just what you’re looking for."

-The Audio Beat

“… the high frequency of that kind of transparent, calm, delicate, crystal clear and flowing feeling actually made me feel like listening to a diamond tweeter. The design skills of the party's development team are unfathomable…”

-Audio technique

"As expected, the Alumine Five is extremely detailed and distinguishes itself as an accurate full-range monitor that I was happy to rely on when editing recordings. With its gripping dynamics, the rousing joy of playing and the perfectly contoured, rich and immense The lively low-frequency range first surprised me and then inspired me. At Stenheim, having fun listening to music comes first!”

-Hifi Statement

"The Alumine Five sets itself apart by offering traditional high-end audio strengths, very wide bandwidth, excellent spatial performance, and freedom from gross colorations, with the drivability and consequent good levels of touch, force, and musical momentum that are seldom associated with loudspeakers of contemporary design and manufacture.”


“The real magic of this speaker is in the focusing, layering and vocal presentation. We can say that this monitor excels perfectly in those areas. Voices are unprecedentedly realistic and stable between the speakers and possess a frightening realism.”

-Alpha Audio

“The Stenheim Reference Ultime has leap-frogged a host of well-established competitors to jostle for position right at the head of my To Be Taken Seriously list. Competitors and customers alike should take it equally seriously. It is quite capable of shocking, surprising, beguiling or just plain seducing . . ."

-The Audio Beat

“I could have stayed in this room for hours, which wasn’t possible at a show, especially one the size of AXPONA. Maybe I should say that I could have listened to this system for hours as it produced no listener fatigue. While the Alumine Three is a modern speaker design in every way, it also has the relaxing sound of many vintage speakers with rich tonal colors, beautiful vocals and well-controlled bass.”

-The Audio Beatnik

"Difficult to replicate the delicacy with the right sense of elegance! The performance of the strength of 3 frequencies (high, mid, low) is super balance and let listeners is on the top of the sound stage from this powerful pair speakers. You always can discover more from this pair of speakers"

-Audio Art

“(…) when I listen attentively , I find that the analytical power of ALUMINE THREE is absolutely superior among the speakers of the same price, because not only the change of music, but also the sound of the pianist's breathing, and the ultra-thin sounds that are triggered when the keys of the piano move have all manifested themselves.”


“The Three is a compact, exceptionally built, and easy to drive loudspeaker that fits into real rooms, with the heart of a large horn system and touches of electrostatic transparency thrown in for good measure. At, or near the top of finest compact loudspeakers available today, and one that joins the small club of products I’d recommend going out of your way to experience”

-The Absolute Sound

. But the Stenheims go deeper than that. Not only do they provide sublime sound, but they resonate with my life as an audiophile. They capture all of the qualities I’ve pursued over the last 40 years, and I highly recommend them.”

-The Part-Time Audiophile

“The Alumine Five may have reduced image height some and was a bit bottom-up in balance, but it showed none of the flashes of brightness or of megaphoning that I heard so often with other displays. Simply an excellent balance of all criteria, and excellent sound.”

-The Absolute Sound

"The low-frequency control is excellent, and the cleanliness is unimaginable. The overall experience of listening to the Stenheim Reference Ultime Two was invaluable.
