I wasn´t really interested in DSD a day ago....  but when Qobuz made it possible to download DSD i started to read up on the DSD subject. I feel a bit embarrassed to ask this question since it feels like i might be missing something...: If i am not mistaken it is possible to upsample qubuz streams to DSD using Roon? If that is the case, does that mean that i could do that on a "computer" (Roon Core) on the network and then send DSD via my router (WiFi) into my WiFi reciever which goes into my streamer. (that is my setup, as seen in my signature) If that is the case it must mean that i get DSD upsampling without the processing noise associated with upsampling, since i am not physically connected to the Roon core, or am i missing something? I understand that i also need a true one-bit DAC for the best result. Any help in explaining this would be appreciated! |

Thank you MartinT! Let me also then add some more context which basically is even more questions about DSD. From what i understand DSD is actually more simplistic and less noisy due to being less process heavy to decode than PCM? (this is a question) Being part of this forum, and becoming a total digital domain noise nerd, this concept feels appealing if you manage to feed the one-bit DAC with a very clean DSD signal. Does this make sense? |

As I said elsewhere, DSD is easy to decode. I used to own a Sony SCD-1, the first SACD machine, a beast of a player. Playing SACDs, which are DSD encoded, it was easy to hear them sounding superior to CDs (although not by as great a margin as you think). That's my sum experience of DSD, but it's a good sounding format. The Sony SCD-1 that I used to own.  |

Since BubbleUPNP took over on my main system for SQ reasons, Roon has been relegated to the secondary systems around my home. Roon easily manages DSD which, as you said, is marginally better than Redbook 44.1 music files. Since Qobuz' availability of DSD is quite new, I haven't yet got around to playing it. I will say that Roon's integration of Qobuz is excellent so this will be of interest to those using both. Will be taking it up shortly and will post impressions here on this thread. It's wonderful to see music playback technologies advance on all fronts these days... |

The sum of all parts is of course what matters in the end and there seem to be a lot of people saying that Roon also can have a small negative impact, as you are saying, so then i also need to account for that... I assume it is the fact that Roon is a bit more process heavy (more meta data) also on the end-point side, than if running a leaner app in your streamer/bridge, or is the theory something different? |

I'm not entirely certain of why Roon differs from BubbleUPNP in playback quality but your suggestion of a leaner resource demand may well account. I found upsampling with Roon to be a waste of time but your experience may differ.
Using HQPlayer with Roon is quite different from using Roon player alone. Using HQPlayer to upsample to DSD is an approach that I enjoy from time to time as it has a very favorable impact on image and soundstage.
For me in my main system BubbleUPNP just seems to have the best overall dynamic presentation so it has become my daily driver... but I do miss Roon's excellent front end.
Be sure to let us know your experience as you move ahead, Tobias.

Martin, the gap in quality feel between opening the flimsy plastic case of the CD and then put it into that overbuilt beast is pretty amusing.

Be sure to let us know your experience as you move ahead, Tobias. I agree that upsampling is generally often a bad idea, if you have a low noise floor, since it ads processing noise (i believe). But if that processing noise can be cleaned up(which is very hard...), or is not done on your physical network, then it should not matter in my mind. Another idea could be to do the upsampling in the cloud i guess. If you could run your Roon Core in the cloud, and do the upsampling there. Then we could receive that DSD stream as any other stream via our normal network to the Roon Client. But maybe i am missing something... |

Tobias, if you are interested in upsampling you should have a look at HQPlayer. Some get impressive results with this excellent player... and it integrates with Roon!
