Our Thoughts RADAR AI

This is a buyer’s market at the top end, and this asking price is ambitious versus the recent EUR comps: €1,650 sits above the €1,474 75th percentile, while the median is only €151. That makes it a stretch unless these are genuinely exceptional examples with proven originality, strong cosmetics, and a presentation that justifies collector money.

That said, vintage Siemens/Klangfilm pieces are sought after for a reason: they’re rare, historically important, and can sound very coherent and effortless when properly restored. If the drivers are original and the cabinets are clean, the upside is real. At this level, I’d want clear photos, driver IDs, and confirmation of working status and any restoration before paying up.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Siemens

Siemens is a German industrial and technology company founded in Berlin in 1847 by Werner von Siemens and Johann Georg Halske. Its heritage is firmly rooted in electrical engineering, beginning with the pointer telegraph and expanding over more than 175 years into a global electronics and infrastructure giant. While not primarily an audio brand in the consumer hi-fi sense, Siemens has had long-running relevance in communications, broadcast, and professional electronics.

In audio, Siemens is best associated with professional and industrial electronics, communications equipment, and historically with parts and tubes rather than with mainstream hi-fi products. It is not known as a major maker of amplifiers, speakers, turntables, DACs, headphones, or cables for the consumer market. Where the name appears in audio circles, it is usually tied to vintage German valves/tubes, broadcast components, or related technical hardware.

As a hi-fi brand, Siemens sits outside the usual high-end or mid-tier consumer landscape. Its reputation is strongest among collectors, engineers, and vintage-audio enthusiasts who value German-built components and historic tube gear. For buyers seeking modern audiophile separates, Siemens is not a primary brand; for those hunting classic European parts and legacy technical quality, it has real cachet.
