Simulate the warmth of the analog era.
Worth taking seriously

This focus stems from a brand legacy spanning over half a century. In 1960, founder Joachim Kiesler and two watchmakers established the PGH cooperative in Geithain, Germany, beginning with technical services before launching their own R&D line in 1966. By 1972, the enterprise was nationalized and renamed VEB Musikelectronic Geithain, during which time it introduced several classic amplifiers and speakers; multiple products earned East Germany's authoritative quality certifications, while the RL 900 monitor speakers were hailed by the industry as "masterpieces of music." In 1992, the company completed privatization and officially became ME GmbH, carrying forward its craftsmanship and acoustic heritage. With innovative technology, it once again won Saxony's Economic Innovation Award, continuing the brand's legendary story.

Equipped with MCDS coaxial technology for a fatigue-free listening experience.

Our Studio and Hi-End series feature our proven, continuously refined MCDS-Coax (Minimum Coloration Directivity Control) coaxial drivers. This point-source design delivers key advantages: uniform, color-free sound and unparalleled imaging and soundstage performance. These characteristics enable extended listening sessions without fatigue.

Achieve unrestricted speaker placement with K-technology (Heart-shaped Low-frequency Directional Control).

In enclosed spaces, sound reflections from walls cause problematic interference in the low-frequency range. While users often attempt to mitigate this through strategic placement, such optimization is limited by many factors and rarely succeeds. Our "K Technology" (named after the German word for "heart-shaped") delivers exceptional performance even in acoustically challenging rooms. Experts from Saxony achieve this by integrating an acoustic propagation element at the rear of the enclosure that attenuates backward sound radiation by more than 10 dB. As a result, reflections behind the speaker are significantly reduced, making interference virtually imperceptible.

Early REVOX became legendary for its reel-to-reel tape decks. The A77 and B77 series set the standard for the analog audio era, while its sister brand, Studer, served professional recording studios where countless iconic albums and artists were recorded. Today, the fully redesigned and upgraded B77 MKIII stereo reel-to-reel remains an enduring masterpiece for analog enthusiasts. Our product line now spans reel-to-reel decks, amplifiers, turntables, high-end speakers, and the STUDIOMASTER multi-room intelligent audio system. We also manufacture our own premium master tapes, ensuring complete sound control from source media to playback systems.

The REVOX B77 MKIII delivers uncompressed, uncolored sound reproduction, blending precision mechanical engineering with minimalist, timeless design. Built on a sustainable philosophy of longevity, serviceability, and cross-generation compatibility, it never compromises to fleeting trends. Bridging the analog and digital eras, the B77 MKIII is both an iconic symbol for audiophiles and the preferred solution for multi-zone music systems in high-end homes and commercial spaces—faithfully bringing studio-quality sound directly to listeners.

All products are manufactured in France. The lineup includes four reel-to-reel tape models—SM900, SM911, LPR90, and LPR35—plus C60 and C90 Type I iron oxide blank tapes. They cover use cases from studio master production, multi-track professional recording, home recording, long-term archival storage, to mixdown reissues. Compatible with nearly all modern and vintage reel-to-reel decks from Studer, Revox, Nagra, and more, these tapes match the electrical characteristics of classic brands like BASF and AMPEX.
