@acko: Hi again ... I've been reading on & off in this thread so might have missed it .. but can I ask you to briefly say what the concept of your DSD DAC is? Is it a combined DSP & DAC (what sort of DAC) solution or something else?

Just a brief description would be fine.

Cheers,

Jesper

It is combined DSP DAC. I think that is what all modern DACs are.
Btw, As I see it even this 'NoDAC' approach has DSP - all happening in HQPlayer hosted on PC

Hi, that is exactly my idea too, using HQPlayer and/or Acourate for DSP.

A bit of topic but concerns te connection, how to feed it:
Question for me is, after per channel say for a 3-4 way speaker done that DSP in PCM and than to DSD signal, how to transfer it from PC to the 3-4 number of mono DACs (mono's which I like anyway!).

I was hoping AVB via CAT6/7 would be something I guess, but as far as I know the 10/100 ethernet endpoints can do a max of 8ch@48kHz, 4@96, 2@192, 1@384 and no idea about 24bit or 32bit and no idea either about DSD. Anyway a better alternate should be 1GB endpoint without such limits.

It is taking longer than expected but rest assured this will roll out eventually.

Also, for those who have PM'ed me you can connect this DAC to any media player and you do not need a high power PC running HQPlayer. The built-in upsampler converts PCM to DSD and DSD to DSD (untouched) automatically.

If you are streaming Tidal, again just a low power PC with USB direct to DAC for DSD output from Tidal 44.1k No need to go through Roon-HQPlayer NAA or Linux boxes.

Since upsampling and transcoding is taking place at the point of consumption, it is also very light on the network. For tests I am using a 1MHz Netbook and music streamed (including Tidal) over home wifi.

I am looking at adding a second I2S port to make it more useful so there is some additional work.
