Estelon X Diamond Mk II Loudspeakers

To many audiophiles, this one included, luxury loudspeaker maker Estelon has largely been a mystery. What I knew about Estelon before this review—and I follow the upper end of the hi-fi market closely—was entirely superficial: They’re based in Tallinn, Estonia, in northern Europe; before COVID-19, they displayed their wares at Munich’s annual High End show; the shapely forms of their speakers are often described as elegant; and those speakers are not inexpensive.
