This is my new standard in digital, a beautifully engineered DHT piece in the tradition of Allnic long line of high performance phono, preamps and amplifiers.

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.

I2S input will be provided in the near future. This separate system will be connected to DAC by a proprietary method through the AES port and provide not only PCM but also DSD. This system has the capability to support extreme upsample and cross conversion between DSD and PCM. Details will be published on a future date.

Every source component has a word clock that sends an impulse to the D/A converter ‘x’ times per second triggering it to take a sample - this becomes the sampling rate. The precision of this clock determines accuracy of the conversion process which is essential to avoid frequency drift between the internal oscillators of the device.

The D5000 frame clock provides synchronization information to the outside device allowing it to precisely match the D5000 MEMS clock. If word clock input is provided then the D5000 internal system will use word clock for playback. By providing an exact data rate, data overrun or underrun are avoided and this reduced jitter creates clearer transients, pronounced attack, crisp inner detail in the higher frequencies and overall improved stereo image.

Firmware updates are completed through the USB input designated for music data using a special interface unique to Waversa Systems.
