About the TA-A1ES

The Sony TA-A1ES is a premium integrated stereo amplifier designed for audiophiles seeking high-resolution audio performance. It delivers 80 watts per channel into 8 ohms with a wide frequency response of 10 Hz to 100 kHz and very low total harmonic distortion of 0.09%. The amplifier features a Class A push-pull high-current circuit with smart bias control linked to volume position, optimizing sound quality across listening levels. It employs a single pair of transistors per channel to reduce variation and distortion, and includes an FET input buffer and discrete preamp circuits for enhanced clarity and detail. The TA-A1ES offers five line-level inputs including one balanced XLR input, large screw-type speaker terminals for secure connections, and a dedicated headphone amplifier with impedance adjustment. Its chassis uses a frame/beam/base design with a large proprietary toroidal transformer (300VA) and 24000μF capacitance per channel for stable power delivery. The amplifier supports 4 to 16 ohm speaker loads and includes a remote control. It is noted for its clean, detailed, and fluid sound with excellent build quality, though some reviewers mention a slightly laid-back midrange and less rhythmic punch compared to some competitors. Dimensions are approximately 17" W x 5.1" H x 16.5" D, weighing about 39.7 pounds. It was released around 2013-2014 and carries a premium price reflecting its high-end design and components.
