Wunder Audio CM7 Suprema – a professional large-diaphragm tube condenser microphone representing the pinnacle of vintage and modern microphone design. Built as a high-end recreation of the legendary 1950s Neumann U47, the CM7 S combines extraordinarily direct low-end responsiveness with a wide high-end plateau, delivering both the best qualities of a modern microphone and the iconic sound of a vintage classic.
The CM7 Suprema stands as a serious pro-studio workhorse with exceptional tonal balance across the frequency spectrum. Its authentic three-layer grille design features outer large mesh, inner medium mesh, and fine mesh sandwiched between, creating acoustic interplay with the capsule and functioning as a Faraday cage. The precision-engineered M7 capsule features a brass backplate hand-milled in Switzerland to the original 15/10000th inch specification within one-micron tolerance, with diaphragms stretched and glued to the rim—never screwed to the backplate—ensuring unparalleled sonic accuracy.
At the heart of the CM7 S lies a modernized NOS Telefunken EF14 tube, carefully selected from the best production years. The transformer is a historic recreation of early "Large Badge" U47 transformers, wound to original Braunbuch specifications using NOS laminations with authentic vintage Mu-Metal and larger 1/8" bobbin specs. Teflon wire insulation replaces problematic PVC for 100% reliability. Wunder Audio has enhanced their vintage-inspired design with Suprema Silver Gold Oil capacitors—the highest quality available—featuring 99.99% silver and 1% gold metallization. This creates a modern-vintage sound where the spectrum opens up with enhanced sound staging, air, and transparency, resulting in less grain, more fluid sound, and tighter focus. The proprietary PSU delivers clean, stable DC voltage with complete RF/Wi-Fi interference shielding and universal voltage compatibility. Exceptional for vocals, drums, acoustic guitars, and piano, the CM7 S brings out natural sound from any source.
