The Evolution STA-SE sets a new standard in distortion reduction with its Only Distortion Cancellation (ODC) technology and proprietary ultra-low-noise GaN (Gallium Nitride) power supply. This combination delivers exceptional clarity, a deep and expansive soundstage, high dynamic range, and warm, Class A-like tonal characteristics. Featuring a dual-mono stereo configuration, the amplifier outputs 400W x 2 at both 8 Ohm and 4 Ohm loads.
