About the SR-X9000
The STAX SR-X9000 is the company’s flagship electrostatic earspeaker, designed as a modern successor-level statement model with a large round sound element, open-air enclosure, and newly developed MLER-3 fixed electrode structure. STAX describes it as a new pinnacle model inspired by the SR-Ω/SR-Omega concept, with a larger ultra-thin diaphragm, machined aluminum housings, stainless-steel arc assembly, genuine leather contact surfaces, and detachable cables in two lengths. It requires a dedicated electrostatic energizer/amplifier with 580V bias.
