wave reproduction technology. Reproducibility of weak signals is
increased by expanding the 16-bit digital data to 32 bits.
Additionally, the unit is equipped with a 192 kHz/32-bit compatible high
performance D/A converter for converting the digital data expanded by
Advanced AL32 Processing into analog signals.
0High sound quality operational amplifier + current buffer

amplifier.
The output level features a discrete current buffer circuit for fully driving
the headphones.
0Low phase noise crystal
Two low phase noise crystals (22.5792 MHz, 24.576 MHz) are used for
the master clock.
The crystals remove jitter from the master clock and faithfully reproduce
the high resolution sound source by syncing with and switching the
sampling frequency.
