hey that sounds interesting too!

if it is highly compatible to the old AK4396 DAC, who will be first
trying it out?

here's some more information:
"Tokyo, Japan, June 27, 2007—Asahi Kasei EMD today launched the AK4397,
a 32-bit 192kHz high performance audio DAC for professional audio
equipment and top-of-the-line consumer DVD/DVD-Audio/SACD player, AV
receiver and digital mixer product applications. The AK4397 is the
newest line-up of our Audio4proTM product range.

The new 32-bit digital operation block provides a fully 32-bit
processing for the audio interface, perfect linear phase digital filter
and delta-sigma modulator. It allows high accuracy D/A conversion of
32-bit audio signal generated by high accuracy processor such as 32-bit
DSP.

Innovative design techniques include a symmetrical layout for the
left-right switched capacitor DAC and fully separated analog power
routing to avoid any degradation by cross talk and common impedance.
Additionally, own unique switched capacitor DAC with excellent
anti-jitter performance, circuit design to suppress the jitter
generated internally, dedicated power supply pin for clock circuit
result in unprecedented sound quality.

The AK4397 further provides a dedicated input port for direct stream
digital (DSD) data input, sampling rate from 30kHz to 216kHz, fully
differential analog outputs, digital attenuator, de-emphasis filters,
soft mute and zero detection functions. The performance is THD+N of
-103dB and S/N of 120dB. The operating voltage is 5V.

The AK4397 is available in a 44-pin LQFP package. *Function and
software compatibility with the industry standard AK4396 24-bit Audio
DAC means a simple upgrade path for AK4396-based systems.* For a demo
of its high quality sound, the AK4397 evaluation boards and samples are
available now. To obtain more information, contact Asahi Kasei EMD
Corporation, Audio & Video Business Operation, Nishi-Shinjuku 1-23-7,
Shinjuku-ku, Tokyo 160-0023, Japan."
