Sony TA-A1ES High-Resolution Audio Stereo Amplifier (TA-A1ES)
The Sony TA-A1ES amp is designed to give you the best from your High-Resolution Audio. A field-effect transistor (FET) input buffer delivers enhanced sound quality with low distortion. Hear every detail of the song with simplified final stage circuitry that produces a high power output, and bias that’s intuitively controlled by and linked to volume position.
The Sony ES TA-A1ES integrated stereo amplifier is rated at 80 watts per channels (20-20kHz) in 8Ω or 4Ω. The Sony TA-A1ES uses a Class A amplification circuit hooked up to a tracking power supply that delivers only as much power as needed, so almost none is wasted as heat. This innovative amplification technology combines audiophile-pleasing sound with high efficiency for true high resolution audio performance.
The TA-A1ES achieves dynamic output by using a single push-pull amplifier design. The power amplifying stage, which determines sound quality, consists of a single pair of transistors, successfully eliminating the emitter resistance used by conventional amplifiers to suppress overheating. The transistor output drives the speaker directly, reproducing sound with greater dynamics and less distortion.
By including fewer transistors and eliminating the emitter resistor and coil & capacitor needed in the amp’s final stage circuitry, Sony has reduced the distortion that affects the quality of your music. This means the amp can deliver a higher power output, so you can push up the volume and enjoy great, undistorted, High-Resolution Audio.
High-Resolution Audio technology delivers every subtlety and nuance of a song in rich, immersive detail. With Digital Sound Enhancement Engine (DSEE) technology, you can hear all your music, even compressed files, in quality closer to the original recording.
The integrated amplifier has been fitted with a FET input buffer and discrete circuit for the pre-amp. This reduces the effects of distortion while enhancing the sound quality of High-Resolution Audio. As a result the integrated amp can produce the sharpness and detail that high-resolution audio brings to your music with minimal distortion.
Sony has combined the electronic volume with a discrete buffer amp to enhance the overall sound quality by reducing the gain error experienced by conventional amps. For long-lasting, high performance, the TA-A1ES intelligently controls the bias by a volume position to heighten the sound quality. The built-in smart BIAS system controls the amp’s BIAS based on the volume position. In doing so, the amp is able to utilize a field that experiences good transistor linearity without generating heat, so the sound quality always remains true.
A frame beam base chassis combines a conventional frame beam chassis with a transformer base to provide exceptional rigidity and stabilization. This exceptionally stiff frame helps the amplifier provide highly accurate sound with little distortion.
The Sony ES TA-A1ES integrated amplifier is fitted with both balanced and unbalanced inputs. There is one balanced stereo XLR input for connecting a high-end CD/SACD or Network player. There are also four unbalanced stereo RCA inputs for connecting your CD/SACD player, Network player, external DAC, and more.
Heavy Duty Binding Posts: The Sony TA-A1ES integrated amplifier features heavy-duty binding posts to connect a single pair of speakers. The binding post speaker terminals will accept bare wire (up to 10AWG), pin-connectors, and single banana plugs. The integrated amp supports speakers between 8Ω to 4Ω.
To reflect the growing popularity of premium-quality headphones, this amp includes a specialized discrete amp with gain optimized to match headphone impedance. The impedance can be switched among the following settings.
The Sony ES TA-A1ES comes with an IR remote control for wireless operation of the integrated amplifier. The remote offers Power On/Off, Volume Up/Down, Source Input (1-5), Mute, and Display controls.
If you connect this integrated amplifier to another Sony component with an IR repeater output jack, you can operate the amplifier from the component connected.
The integrated amplifier switches to standby mode automatically when no sound has been output for about 10 to 15 minutes.
