About the HD970

The Harman Kardon HD 970, produced approximately between 2005 and 2007, is a high-quality CD player designed for audiophiles seeking precise and clean sound reproduction. It employs a multi-level Delta-Sigma digital-to-analog converter (DAC) with 8-times oversampling digital filtering, specifically using the AD1955 DAC chip, delivering a frequency response of 20 Hz to 20 kHz with minimal distortion (<0.0009% at 1 kHz) and a dynamic range exceeding 116 dB. The unit supports playback of standard CDs, CD-R, and CD-RW discs, as well as MP3 files, and includes features such as shuffle, repeat (title, CD, A-B), and programming up to 32 titles. It offers two digital inputs (optical and coaxial), digital output (coaxial), and line-level analog outputs (2 V RCA), allowing integration with external digital sources and systems. The HD 970 also features a dimmable multifunction display, remote control, and a robust chassis with a brushed aluminum front panel to reduce vibrations. Weighing approximately 4.4 to 4.6 kg, with dimensions around 440 x 63-110 x 325-332 mm, it combines elegant design with audiophile-grade components such as the ADSP-BF 532 BlackFin DSP and high-quality operational amplifiers (OPA2134 and OP275). The player is noted for its smooth, silky sound and excellent price-performance ratio in its class. It remains a respected component for high-fidelity audio playback and digital-to-analog conversion.
