Even if you stuff a microphone full of premium components, when the capsule isn’t right, nothing is – it’s that critical. Knowing this, Warm Audio went to great lengths to recreate the capsule from the original ’67, making sure that ours performs the same way, has the same frequency response, and contributes to the same chewy character. That meant not only ensuring that the WA-67 design was accurate but applying that design to modern construction materials to achieve the same vintage tone. They also chose to craft the entire capsule assembly out of brass, including the tensioning hoops, just like the original design. While it’s more costly and time-consuming to construct capsules this way, Warm Audio felt it was critical to go the extra mile to achieve extremely accurate sound. The results speak for themselves; the award-winning WA-67 sounds absolutely stellar and excels against vintage and modern microphones costing much, much more.

The EF-86 tube is well-known in the industry for having characteristics that are consistently flattering to audio sources, and it’s one of the reasons why the original ’67 microphone remains sought after (and why some modern audio manufacturers use it in their own hyper-expensive microphones and preamps). Warm Audio knew that it was critical to get absolutely right in the WA-67, and they’re thrilled with the results.

Going even further, in order to accentuate and complement the custom capsule and EF86 tube, Warm Audio used top-shelf components to complete our version of the original circuit. They used high-bandwidth polystyrene capacitors, as well as boutique polypropylene caps from Wima and a large output capacitor from Solen. Just as important in a tube design, Warm Audio also used a custom large-core transformer from Lundahl in Sweden, which plays a significant role in the buttery smooth high-frequency response and huge three-dimensional sound of the WA-67. The microphone is also encased in a beautiful nickel-plated brass body and headbasket, which provides strength, additional shielding from extraneous handling noise, and the ultimate in audio performance.

Last but not certainly not least, the quality of the 7-pin cable that connects a tube mic to its power supply is also of paramount importance – it carries both audio signals and voltage for the tube on different pins, which means that it plays an integral role in the performance of the microphone. That’s why Warm Audio has 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.
