A new highlight in analog audio technology

The Revox B77 is a true icon in the audio world. Famous and awarded for its outstanding sound reproduction and high-quality, sustainable construction, it sets the standard for analog audiophile excellence. As a Revox product, it reproduces music exactly as the artists recorded it in the studio. With the new B77 MK III Stereo Tape Recorder, the Revox development team has now redesigned this special product and improved it with significant new features.

The entire audio electronics have been optimized with the components and simulation options available today. Proven components have been retained, such as improved original Revox tape heads with a significantly longer service life and the unique Revox motors. All new details, such as the audio technology for even better sound reproduction and recording quality, the precision-manufactured, high-quality tape heads, the pressure roller, a digital counter, playback capability for all common tape standards, XLR IN/OUT, and a wide range of connection and optional expansion options have been perfected by our developers, technicians, and designers. The B77 MK III is manufactured in the Revox factory in Villingen.
The result is an extraordinary sound experience and an immediately recognizable yet visually new highlight.

Built for eternity

Like its predecessors, the new B77 MK III is manufactured to the highest quality standards as an audiophile masterpiece and visual work of art and stands for demonstrable sustainability like no other audio product. The high level of production and quality control required for the B77 MK III means that no more than 20 machines can be produced per month.

Created for the extraordinary

With the B77 MK III, the Revox development team has once again decisively extended the limits of what is possible in analog audio technology. Therefore, this new Revox B77 is something unique and created for those who are looking for the best and therefore rely on the incomparable sound and manufacturing quality of Revox!
The unique music experience is raised to a whole new level by the perfectly matched B77 MK III and the Revox Analog Master Tapes. A must for every music lover who wants to experience the best possible music quality at home.
