I created this topic to discuss the brand new Violectric DAC V850

Violectric to introduce a new D/A converter: DAC V850
Violectric will introduce a new D/A converter during the May 2015 HiEnd exhibition in Munich Germany.
The case and the front panel will share the familiar look of our well known DAC V800.
The DAC V850 features 4 digital inputs: balanced AES/EBU via XLR, coaxial SPDIF via RCA, optical via
Tos-Link, and Asynchronous USB. All inputs are capable of PCM up to 24 bits at 192 kHz.
Topology:
The digital signal is first routed to re-sampling circuitry where virtually all incoming jitter is eliminated.
Then up to 4 times up-sampling can be selected from the front panel.
This process can be completely disabled or set to “best” operation which means that all incoming digital signals will be normalized to 96 kHz.
We have found this to be the optimal frequency to achieve the best audio quality when re-sampling lower bit rate data.
A digital output is also provided which mirrors either the active input signal or the digital signal that has been processed by the re-sampler.
Our design features a 32 bit double mono converter architecture which consists of two 32 bit (PCM1795) converters for each channel.
This serves to enhance the dynamic range and minimize distortion.
The analog output circuitry is fully balanced from the D/A converters to the analog outputs.
This is very similar to the circuitry design we used in the DAC V800 but, with further refinement in the output stage.
The maximum balanced analog output level may be set internally to +24 / +18 / +15 / +12 / or +6 dBu to ensure a perfect match with your other equipment.
The unbalanced analog outputs will always be 9 dB lower compared to the balanced output setting.
The volume control is again all digital just like we used in the DAC V800.
There is no scratching, no channel imbalance, and no reduced crosstalk which can be the case with an analog volume implementation.
This is why we prefer digital all the way through our design. Yes, there is some reduced resolution when lowering the volume.
However since we first up-sample the input to 32 bits we have at least 8 bits with no definitive content.
This gives us 8 x 6 = 48 dB of gain reduction available to lower the output volume and prevents any degradation of the original digital signal.
The DAC V850 may be equipped with an optional remote control for volume and input selection.
A motor driven potentiometer serves to set the attenuation.
The DAC V850's front panel will be available in BLACK and SILVER.
The estimated price will be around 1175 Euro excl. VAT, the remote control option adds 210 Euro excl. VAT.
