The sDP-1000 is a high-end D/A converter and preamplifier with a USB audio function to support DSD playback, a high-performance clock circuit, a battery power supply and a high performance preamplifier. The design is compact and classy. Various digital and analog connections are available. The OLED display window shows the information related to usage and is easily controlled by the remote or faceplate switches.
USB audio uses an asynchronous mode to connect the digital audio source device such as a PC. It can play back a 32 bit/192KHz PCM signal (maximum) and DSD signal. In addition, the sound quality from the input source can be improved by the specially designed high performance clock and 32 bit up-sampler circuit.
All audio circuit parts, including the DAC and preamplifier volume control, are fully balanced circuits. No coupling capacitors are used in the audio signal path since that would cause distortion of the sound quality. The design allows for clear, excellent and high resolution sound.
With dual battery packs as a standard feature, one battery provides power, and the other charges and switches between these functions automatically. The sDP-1000 will work continuously via battery power only. There are already many DAC’s on the market, but the sDP-1000 is incomparable. The sDP-1000 is a perfect centerpiece for your high-end audio system.
