About the TA-N9000ES

The Sony TA-N9000ES is a 5-channel power amplifier released in 1998, designed to complement the TA-E9000ES preamplifier. It features a robust build with a direct ground drive system that improves power supply speed and sound quality. The amplifier delivers 120 watts per channel into 8 ohms in stereo mode, with a total harmonic distortion (THD) of 0.013% or less, and supports bridged (BTL) mode for higher power output. It can operate in 5-channel, 4-channel, 3-channel, or 2-channel modes, with flexible input options including an extra 2-channel input for stereo preamplifiers. The chassis uses Frame and Beam construction for rigidity and vibration reduction, and a large "Stress Free, Linear Core" transformer ensures stable power delivery. It weighs approximately 24 kg and measures 430 x 173.5 x 453 mm. The unit was manufactured in Japan from 1998 to 2003 and is known for its excellent sound quality, low distortion, and high build quality, making it a sought-after amplifier for high-fidelity surround sound systems.
