Ralph Werner has posted a review of the Zendo Cable (Mundorf) interconnects (starting at €331/349) at 6moons. His conclusions:
Zendo’s line-level cables are ultra transparent operators in an elevated but far from bleeding price class. Tonally and on taste they are most suitable for neutral to slightly warmer systems where they will really impress with high resolution and exacting sorting. Sparkling, immediate and direct are all fitting terms. That’s why the Zendo Cables will remain in my system.
