For the SR-X9000, the Stax developers claim to have found a way to improve the "MLER 2" electrodes used in the SR-009S even further. The new "MLER 3" electrodes now have a significantly larger metal grid, which is said to completely eliminate reflections. In addition, the surface area of the ultra-thin plastic foil has been increased by 20%.
The housing is made of intricately crafted aluminum and is supposed to be vibration-free. For the ear pads, Stax uses high-quality, especially soft sheep skin leather. This is said to have excellent breathability and ensure that the SR-X9000 can be worn for extended periods of time.
In Germany, the SR-X9000 is supposed to be available from mid-October at a price of around €7,250.
