Network Bridge Discussion Thread

Interesting review from Darko

So the interior main board / network card is the same down the whole range o dCS streaming products, from the Vivaldi Upsampler / Streamer to the NWB , that is great info , and also states that it is possible to squeeze a few drops more out of the NWB if dCS wanted to, as i see it.

Then Darko also mentions that he is using the non bit perfect vol. control in the Mosaic app, so he can use it as an pre-amp if connected to a DAC without volume control. That is not the best way to do it :flushed:

Hello, did you test the volume in Mosaic with your NB ?

If i have tested the volume in the mosaic app?

Yes , and it is not bit perfect and should always be set to 100%

That rather depends if you have a volume control in your setup. Just because it’s not bit perfect doesn’t mean it’s not a valid way to control volume. You might not even hear any of the minute losses anyway. Analogue volume controls have their own losses and distortions, after all.

Agreed.

As far as I am aware Mosaic only sends commands to the dCS streaming component e.g Network Bridge which is where the activity occurs. If I am right then using the Mosaic volume control is activating a digital volume control in Network Bridge, it doesn’t do it in the app.

As for the question of bit perfect, no digital volume control is bit perfect below 0dbfs as they work by reducing bit depth. The interesting question is not "is it or isn’t it " bit perfect but whether the outcome produces audible loss of resolution. In earlier generations of dCS product (e.g. Scarlatti/Paganini) they asserted that loss of resolution would only start to occur with the volume control set below -20dbfs. I have to say that I was never able to detect any loss of resolution even if the volume control was set below this as the increasing reduction in volume made my hearing less and less able to detect any such loss :thinking:

According to dCS them self’s the volume should always be set to 100% of the NWB to maintain full resolution.

" According to dCS them self’s the volume should always be set to 100% of the NWB to maintain full resolution."

Yes, that’s what I said " no digital volume control is bit perfect below 0dbfs ". However we are listening to music not looking at numbers ( at least I hope).

So, presumably you do not approve of anyone using the volume control on their dCS DAC as that is just the same as using the volume control on the Network Bridge albeit at a different position on the circuit?
