Hi, i have a Cambridge Edge NQ and A paired to a KEF R7, start using Roon and love it, i just dont understand the upsampling process, doest i makes sense to upsample everything to DSD256 or 384KHz connected to the DAC with USB, i am using Tidal and Qobuz, think i will go with Qobuz, in the DSP Funktion of Roon, Sample Rate Conversion what it the best setting i should use, doest it makes sense to upsample everything to DSD256? Or if i use Custom, upsample everything to 352,8KHz and 384KHz, Its the first time that i have a Amp and Networkstreamer just want to get the best out of it. Or does the upsampling makes sense when i upsample from DSD64 to DSD256, or Flac 48KHz to 384Khz. Some clearance would be nice and thanks in advance … thats all new to me, i read alot in the roon forum but still have no idea 
The best reason to upsample (or not) is better sound quality, if perceived by your own ears.
Depending on what you like and prefer, there is a good chance you will like the music resulting from upsampling your digital input stream, better. But only you can be the judge of that.
Some people prefer a bit-perfect, unaltered input stream into the dac.
Most definitely worth to give it a try.

I upsampled everything to DSD256 it sounds more controlled and pulling the volume up its sounds more clear and compared to non upsampled. I was just worried because it sounds quieter and have to pull the volume up, thought i did something wrong with the settings, thanks for the reply
No, it is quieter. You did nothing wrong.
I’m a simple man.
I think the guys who build a DAC know their stuff (or should know it).
If the DAC benefits from upsampling, they should upsample (as most of them do),
This is not magical, unknowable technology.
