The Sony CDP-991 is a CD player that was introduced by Sony Corporation in the late 1980s. It is considered a high-end model due to its advanced features, such as digital signal processing (DSP), 16-bit/44.1 kHz resolution, and a powerful analog output stage. Some notable features of the CDP-991 include:1. DSP: The CDP-991 was one of the first CD players to incorporate digital signal processing (DSP) technology, which allowed it to enhance the audio quality and reduce noise and distortion.2. High Resolution: The CDP-991 used a 16-bit/44.1 kHz digital-to-analog converter (DAC) to provide exceptional CD playback. This resolution was significantly higher than the standard 12-bit/44.1 kHz found on most CD players at the time.3. Analog Outputs: The CDP-991 had both digital and analog outputs. The analog outputs were driven by a toroidal transformer and a capacitor network that provided a high-quality, low-noise signal.4.

This was a useful feature for audiophiles who preferred a more centered sound image.5. High-Quality Construction: The CDP-991 was built with high-quality components and construction techniques, which contributed to its exceptional sound quality. It also had a premium finish that complemented its high-end status.Overall, the Sony CDP-991 was a top-of-the-line CD player that set a new standard for audio quality and features. It earned numerous accolades from industry experts and audio enthusiasts, and remains a sought-after collectible among audiophiles today.
