Allnic’s junior D3000 DAC designed down from the flagship D5000. This is a rock solid performer with great value for money at the pricepoint. More to follow soon.
The D5000 is very unique in today’s DAC world because most of its components are not from any routine audio market source except the DAC chips. The USB interface, SPDIF receiver and high end upsamplers are all specifically customized for this application. D5000 uses very unique technologies for audio signal processing. The clock does not directly connect to the DAC chip. Instead, the audio processor uses clock alignment algorithms that determine exact alignment for the DAC chip in a real-time manner. The ES9018K2M SABRE 32 Reference DAC chip is a high performance 32-bit, 2-channel audio D/A converter with sampling to 32/384 kHz, 128 DSD and uses a 1.5 MHz upsampler through a field-programmable gate array USB interface.
While most ES9018K based DACs use the dac chip for audio processing, the D5000 has a proprietary internal processor that performs real time PCM upsampling or upsampling and conversion to DSD. The SABRE Reference DAC chip only performs the digital to analog conversion.
Real-time PCM to DSD conversion function is implemented when “conversion” is selected. All input samples are converted to 128 DSD with an internal 5.6 MHz/32 Bit upsampler and DSD converter. When de-selected, input audio sampling is either upsampled, if selected, or bypassed to the DAC chip.
The USB interface is implemented through custom hardware by Waversa Systems and is UAC2 standard compliant. This provides very clean audio through complete galvanic isolation, thereby stripping the digital signal of any PC noise commonly created by the server’s internal power supply. Thesycon driver is provided for Windows application. Drivers are not required for Mac/Linux.
