Why you want upsampling and upconversion in a server and why it sounds way better!


One of Roon's and Jrivers best advantages is the ability to digitally reprocess your data. 

With an appropriate server you can take for example a 16 bit 44k Tidal stream and reprocess that data stream to DSD or to reprocess to 24bit 192k, 384k, even up to 768k.

In our tests almost accross the board most listeners perfer DSD or high res PCM data streams.

The counter arguement is that if you start with 16 bit 44k sample you can't do any better as that  is the source.

Going through Facebook we got a post that showed the Lumiere brothers first film shot in 1894 with a steam locomotive. 

The second video showed the same Lumiere video reprocessed using AI to create a 4k video stream out of the same video footage. 

The first video is the native source the second shows the reprocessed video the differences aren't subtitle even if you reprocess the native video you are able to extract a signifigantly higher quality image. 

We have been saying this for years even if you don't start out with a true high res source through the magic of computer reprocessing you can create a pseudo high res data packet that still sound far better than ifs original form.

Watch the video and see what you think. Sure it is always best to start with a true high resolution image but in the case of not having a true high resolution music fille the ability to use digital reprocessing can create a signal that will sound far better providing that your dac and server are up to the task.

I only ever used coax and toslink so maybe it is a function of the USB input from n the earlier Brooklyn DAC?
George.
Pretty much a major disaster and glad you are ok but what a tragedy that can partly be laid at Man's door.

I should keep away from a few threads here where some members are vociferous on climate change being a non issue. What little respect I had was flushed right down the toilet right there and then.

Yes condolences to the families of all who lost their lives in the fire fighting.
And to all those who lost so much in every aspect over in Australia.
@georgehifi 

Good to see you back.
Was a little worried by your absence in light of the fires.
Hope all is well.

I remember you saying previously that your Brooklyn gave issues occasionally when switching between differing resolution rates.

Not sure if that is a trait of the Brooklyn though as I cannot say I ever had it happen on my Brooklyn?
Odd.
