Brand: Sony

The Sony TA-F650ES (model number ESD in some countries) is a high-end audio amplifier designed for audiophiles and home theater enthusiasts. It is part of Sony's ES (Essential Sound) series, which is known for delivering exceptional sonic performance and build quality. The F650ES has a maximum power output of 2 x 220 watts into 8 ohms, and it supports a range of digital and analog input sources. Some key features of the F650ES include:1. Dual Analog Devices (AD) SHARC DSPs: The F650ES uses cutting-edge SHARC DSPs (Digital Signal Processors) from Analog Devices, which are well-regarded in the audio industry for their low noise and high fidelity. The onboard DSPs provide advanced processing capabilities, including room correction, crossover network compensation, and compatibility with Digital Streaming Audio (DSD).2. MX Celestial Audio Soft-dome tweeters: The F650ES utilizes premium-grade MX Celestial Audio soft-dome tweeters, which deliver smooth, extended high-frequency response. The tweeters are mated to aluminum phase plugs, which improve dispersion and provide excellent transient response.3. Toroidal transformers: The F650ES employs two massive toroidal transformers to provide stable and low-noise power to the amplifier. Toroidal transformers have a small footprint and produce less magnetic interference than traditional "E"-core transformers, which makes them ideal for high-end audio applications.4. Rigid external power supply: The F650ES comes with a separate external power supply unit, which helps to isolate the amplifier's power supply from any external noise or interference. The external power supply also provides clean and stable power to the amplifier, which is essential for achieving exceptional sound quality.5. Dual bi-amp terminals: The F650ES has two pairs of bi-amp speaker terminals, which allow for easy connection of bi-wire or bi-amp speaker systems. The bi-amp terminals also facilitate more precise control over the speaker drivers, which can result in better soundstage and imaging.In terms of input/output connectivity, the F650ES supports a range of digital and analog sources, including:1. Balanced XLR inputs: The F650ES has two sets of balanced XLR inputs, which are ideal for use with digital audio sources like CD players and DACs. Balanced inputs provide superior noise rejection and low-level signal handling than unbalanced inputs.2. USB-B input: The F650ES has a USB-B input for connecting to a computer or digital audio source via USB. The USB input supports multi-channel audio, and also facilitates the use of Sony's Network Module (EsNet), which allows for streaming of DSD and PCM audio files.3. Phono input: The F650ES has a dedicated phono input with adjustable loading for use with turntables and analog vinyl sources. The phono input supports both MM and MC cartridges, and provides excellent tracking ability and low noise performance.4. Preamp outputs: The F650ES has two sets of preamp outputs, which allow for easy integration with external amplifiers or ShareStation multichannel amplifiers. The preamp outputs facilitate polyphonic processing and help provide precise control over speaker drivers.5. Pure Direct mode: The F650ES has a Pure Direct mode, which turns off unnecessary circuits to minimize signal path length and reduce electronic noise. Pure Direct mode also helps to preserve the natural tonality and dynamics of the music.In terms of design, the F650ES has a sleek and modern appearance, with a bold black finish and high-quality build quality. The amplifier also uses large-gauge copper-plated oxygen-free copper (CuOFC) internal wiring, which provides excellent conductivity and low noise transmission.Overall, the Sony TA-F650ES (ESD) is a high-performance audio amplifier that delivers exceptional sound quality, flexibility, and build quality. It is an excellent choice for audiophiles and home theater enthusiasts who seek the very best in audio performance.
