Advanced Audio Microphones
Advanced Audio Microphones is the imprint of Dave Thomas, well-known mic modder from British Columbia. The company imports a handful of tube and FET mic models from one of the higher-end factories in China, then individually tests each mic upon receipt.
The tube mics are upgraded at the AA shop, with circuit improvements and in some cases new output transformers. Customers have the option of requesting upgraded capsules, too; Advanced Audio offers selected capsules from Peluso Microphone Lab.
Dave Thomas’ mods to the Alctron HST-11A (and clones) are well-known and well-regarded around the web, and have spawned a commercial product, the AA CM-12.
