18-Bit Technology Withstands the Test of TimeWhether they use Bit Stream or 18-bit digital technology, Harman Kardon compact disc players are distinguished by superior internal layout, quality components, and excellent power-supply and grounding-system design.Harman Kardon\'a 18-bit compact disc players have major advantages over competing brands in the same category. Our units are adjusted in the factory for precise, low level linearity, allowing for clearer, more dynamically accurate, less distorted low level signals. And as with our bit stream players, we use only discrete circuits along the analog audio signal path.
It isn\'t every company that applies the same standards to its compact disc players as it does to its amplifiers. Removing the top from ordinary compact disc players reveals that most dedicate only an averange of five percent of internal circuitry to the analog audio section, while Harman Kardon commits 25 to 30 percent, depending on the model. Buyers can literally see the quality of design.
Discrete Analog Compact Disc Output StagesSound signals travel through analog circuitry before arriving at the compact disc player\'s output jacks. Those stages may employ mass-produced integrated circuits or custom-designed discrete circuits.Harman Kardon uses only discrete circuits along the audio signal path, insuring that the best possible sound produced by the sampling and conversion systems is achieved.Discrete circuits embody close-tolerance resistors, capacitors,, and fast-slew-rate transistors. The benefit is wider bandwidth and minimal negative response, both of which are critical to the compact disc player\'s amplifier stages.
