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." -- truckfighters | Transporter | REDGUM RGASil OCC Silver Interconnects | REDGUM RGi120ENR AMP | REDGUM LS Cable | B&W Nautilus 802 D | >>> Live musicians at the end of my room! <<< ------------------------------------------------------------------------ truckfighters's Profile: http://forums.slimdevices.com/member.php?userid=7852 View this thread: http://forums.slimdevices.com/showthread.php?t=36626
