1 Technical Highlights
1.1 Layout
The power supply units, the CD/SACD mechanism as well as the digital circuits are
strictly separated. The analog output section is realized in dual mono layout.
1.2 Drive
The Digital-Player 541 uses a top class mechanism of the Esoteric model range. It
allows for optimal data read-out of the CD as well as the SACD data.
1.3 DSP (Digital Signal Processor)
A powerful DSP performs the calculations for the upsampling to 24Bit, 384kHz.
The DSD data of a SACD is converted into PCM format during the upsampling pro-
cess. The converted data is extrapolated by a 3
rd
order polynomial algorithm. Addi-
tionally this DSP performs computations for the volume control and the balance set-
tings. Thanks to the 32Bit floating comma architecture of the DSP these calcula-
tions go without the usually increase of the quantification noise.
1.4 Digital/Analog-Converter
The D/A converter section as well as the analog output stages are done in dual mono
layout, one board per audio channel (left/right). We use the Burr-Brown 1792 DAC
which guarantees excellent performance. Only the top quality converter section
which runs up to 384 kHz of the chip is used. The internal upsampling section is
bypassed! Two extremely fast (3MHz) I-V converters per DAC transform the output
currents of the DAC chips in voltages before they get filtered in the following stage.
This ensures optimal conditions in the filter stage as well as for the I-V converters.
