Wunder Audio CM67S

Wunder Audio CM67 Suprema – a professional large-diaphragm multi-pattern tube condenser microphone representing a modern evolution of the legendary Neumann U67 design. Prized for exceptional warmth and smoothness, the CM67 S combines authentic vintage sound with modern enhancements, featuring a switchable cardioid mode relay engineered inside the mic capsule compartment plus eight different polar patterns, making it like having two microphones in one.

The CM67 S delivers a warm and silky sound characteristic of the original U67, making it exceptional for vocals when a smoother sound is desired. This serious pro-studio workhorse excels across multiple applications including drums (toms, snare, overheads), acoustic guitar, and electric guitar, featuring very nice top and bottom end that brings out natural sound from any source. The innovative switchable cardioid mode produces a smoother, more full-bodied sound, with the pattern switch located on the PSU but the actual switch point positioned directly below the capsule compartment.

The CM67 S features a two-piece backplate K67 capsule allowing both diaphragms to be tuned individually and matched for equivalent response. Wunder Audio utilizes a white porcelain mounted ringed capsule—providing low permeability and elasticity, considerable strength, hardness, resonance, and high resistance to chemical attack and thermal shock, improving upon white plastic rings prone to discoloring and impurity absorption. Users can choose between two NOS EF86 tubes: vintage German Telefunken EF86 (emphasizes highs) or vintage special select Phillips tube (lends warmth). The transformer features an elaborate tertiary winding feedback network creating negative feedback through the capsule to the tube for high-frequency de-emphasis, compensating for the natural HF peak of the K67 capsule design—a very special transformer achieving impressive sound. Wunder Audio has enhanced their design with Suprema Silver Gold Oil capacitors featuring 99.99% silver and 1% gold metallization, creating exceptional image depth with enhanced sound staging, air, and transparency. The proprietary PSU features military-spec Grayhill switch, universal voltage compatibility, and complete RF/Wi-Fi interference shielding.
