Allnic Audio D5000 DHT DAC 220-240V [Template]

I purchased this new in 2015 and was most impressed by how musical this DAC is. It is in absolute mint condition and I am the only owner. This unit is the latest upgraded version and includes manual and apple remote.

Asking price: $6500 

This unit is 220-240V but can be factory modified to 110V.

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.
