Brand: Stax

The Stax UA-7 is an electrostatic headphone amplifier that is designed to drive Stax' SR-009 electrostatic headphones with exceptional clarity and resolution. It features a dual monaural circuit design, which allows for a completely separate channel for the right and left ears, providing superior isolation and minimal crosstalk.The UA-7 has a high gain of up to 14dB, which allows it to handle even low-output electrostatic headphones with ease. It also provides adjustable input impedance to suit a variety of sources, including low-output tube amps or high-output solid-state amps.The UA-7 has a wide frequency response of 2Hz to 50kHz (+/- 3dB), and a low output impedance of only 0.15 ohms, for a fast, transparent, and detailed sound. It also features a unique ART (Auto-Ranging Technology) circuit, which automatically adjusts the output voltage to match the input impedance of the connected headphones, eliminating the need for complicated input impedance matching.Overall, the Stax UA-7 is a top-of-the-line headphone amplifier that is tailored specifically to drive the SR-009 electrostatic headphones. It provides exceptional performance, clarity, and resolution, making it an ideal choice for audiophiles and enthusiasts who demand the very best in electrostatic headphone audio reproduction.
