With the HD-990 CD Player Harmon Kardan once again proves that uncompromising dedication to quality coupled with cutting edge technology yields a player at the very summit of the audio world.
The player packs a wide array of sophisticated audio technologies into a low-profile, attractive package. Two AD1955 high performance, stereo digital-to-analog converters enable third generation RLS III. Real-time Linear Smoothing (RLSIII) creates a spacious sound-stage with highly detailed almost textural qualities. The High Resolution Synchronization (HRS) ensures jitter-free reproduction between HRS compatible components. Other impressive specs include a 24-bit/384kHz sample rate converter and 32-bit direct Digital Signal Processing (DSP) mode.
Connectivity includes two digital audio outputs and two balanced XLR outputs with dual Diamond Class A output stages. In addition to compatibility with standard CD formats, the HD 990 is capable of MP3 playback with ID3 Tag information.
For the highest possible CD reproduction, the Harmon Kardon HD 990 is hard to beat.

Comments about Harman Kardon HD-990 CD Player:
This is the best sounding CD player I have ever owned, but what is especially great about it is that I send SPDIF out from my laptop through it to my 2-channel system. Quality from the computer is much better than using the computer's DAC and weak pre-amp. Price is good compared to similar quality players.
