Weiss DAC 204

USB:

Detection:
(Windows only) best option to play to the device : WASAPI
DSD Over PCM setting : DoP 1.0
MQA capability : No

I have a Weiss 204 with capacity up to dsd
64 and 196 kHz
I connect via usb
The local hard drive with library is correctly identified via usb
When playing the albums are identified and it goes ok but not with ISO
The problem I have is with volumen control
No way of getting volumen control and it remains silent until Zi reach maximum and then it goes but at macimun

No can do volume control on DSD files…

Weiss DAC204 converts all DSD to PCM

Apparently, It can convert DSD to PCM *if desired, when an external DAC is connected… However it looks like it is capable to DSD128 via DoP natively.

Downsampling
The USB input signal is treated as follows:

  • Sampling frequencies between 44.1 and 192 kHz are
    passed unaltered.
  • Sampling frequencies of 352.8 or 384 kHz are downsam-
    pled to half of their value, i.e. to 176.4 or 192 kHz.
  • DSD64 or DSD128 signals are converted to PCM with the
    parameters according to the settings of the switches. I.e. a
    sampling frequency of 88.2 or 176.4 kHz can be selected.
    lus a word-length of 16 or 24 Bit. These selection switches
    may make sense if an external D/A Converter is connected
    to the digital outputs of the DAC204. If only the internal D/A
    Converter is used we recommend to set the switches to
    176.4 kHz and 24 Bit.

:notes: :eye: :headphones: :eye: :notes:

1.) There is no setting where the DSD to PCM conversion can be switched off, only the sampling frequency and the word lenght can be selected.
2.) The DSD to PCM conversion is active even when the internal D/A converter is used otherwise the Weiss recommendation to set the switches to 176.4 kHz and 24 Bit wouldn’t make any sense.

Enough evidence that there is no native DSD processing.

Okay… It now makes sense since the DAC is an oversampling sigma-delta architecture… Obviously then, it decimates DSD128 to 24/176.4kHz…

No good way to get playback of any high-resolution DXD files either…

In any scenario, when DSD is being delivered natively or as DoP 1.0, there would not be volume control.
