Warm Audio WA-67 Large-Diaphragm Condenser Microphone

Even if you stuff a microphone full of premium components, when the capsule isn’t right, nothing is – it’s that critical. We went to great measures to reproduce the capsule from the original ’67, ensuring sure it performs the same, has the same frequency response, and adds to the same chewy texture. To attain an antique look, the WA-67 design has to be precise and applied to current materials. Like the original, we made the capsule assembly and tensioning hoops from brass. It’s more expensive and time-consuming to build capsules this way, but we needed to get really realistic sound. The award-winning WA-67 sounds great and outperforms antique and contemporary mics costing considerably more.

The EF-86 tube enhances audio sources, making the original ’67 microphone desirable (and why some modern audio manufacturers use it in their own hyper-expensive microphones and preamps). We knew that it was critical to get absolutely right in the WA-67, and we’re thrilled with the results.

We chose high-quality components to build our rendition of the original circuit to highlight the bespoke capsule and EF86 tube. Used high-bandwidth polystyrene capacitors, as well as boutique polypropylene caps from Wima and a large output capacitor from Solen. We employed a special large-core transformer from Lundahl in Sweden to give the WA-67 its buttery smooth high frequency response and massive three-dimensional sound. A nickel-plated brass body and headbasket provide the microphone robustness, insulation against handling noise, and the best audio performance.

Last but not least, a tube mic’s 7-pin cable, which transmits audio signals and tube voltage on distinct pins, is crucial to its operation. That’s why we’ve partnered with high-end manufacturer Gotham Audio of Switzerland to use their high-end GAC-7 cable with the WA-67. This special cable is integral to the sound and performance of the microphone, and adds the finishing touch to the WA-67 system.
