the design of its CD players? For one, it means Luxman engineers have not forgotten that music is ultimately a collection of analog waves.
The digital-to-analog conversion process is thus the heart of music reproduction in a CD player.

In designing the Ultimate Fidelity CD player. Luxmans goal was to convert digital signals back into
musical signals so precisely as to be indistinguishable from the original source. .0 Until now, the
design of the digital/ analog converter (DAC) in all CD players has been based on a relationship
known as Shannons Theorem. Because this conversion process results in great quantities of high-
frequency noise. a low-pass filter is required to reproduce clean analog signals. However. the filter
inevitably entails some phase shift. To overcome this. engineers have made improvements through the

use of multiple (2, 4, or 8-times) oversampling digital filters. But the solution created new problems

in the form of ringing" distortions. Further improvements have been achieved through the use of dual
