we’re talking about classic tracks from artists as varied as The Beatles, Led Zeppelin, The Temptations and Nirvana. If the mic capsule isn’t right, nothing is. Warm Audio went to great lengths to recreate the original ’67 capsule - same performance, same frequency response and same character as the original. That meant not only ensuring that the hole pattern was identical, but we also made sure to craft the entire assembly out of brass (including the mounting rings) just like the original design. It takes more time and it’s more expensive than using multiple types of material, but we felt that it was critical to go the extra mile on this microphone. The results speak for themselves - the WA-67 sounds incredible.

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. Going even further, in order to accentuate and complement the custom capsule and EF86 tube, we used top-shelf components to complete our version of the original circuit. We 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, we 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 ultimate 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 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.
