Should I upsample?

I think the beauty of Roon is that it allows you to try these things yourself very easily, and let your ears decide. My collection is mostly CD quality, but when I buy new music, I usually opt for the Hi-res version if it is available. I have tried various permutations, but in the end I have come back to leaving things as they are, and letting the Devialet handle such things. Since the D is going to upsample internally anyway, it seems a little perverse to do it externally first. Also, whilst bandwidth isn't particularly a problem with a wired Ethernet connection, it seems logical to think that the less data we stuff down the pipe, the less chance there is of something getting mangled.

I have a number of DSD recordings, and I prefer the SQ of those (sent as DSD64) to listening to the PCM equivalent (assuming the masters were not different) , but I did not find the same magic came through if I converted PCM to DSD in Roon. Similarly, I can't reliably say I notice any difference if I go from 44.1 to 176, but that's just my ears, my system. They all sound good to me.  

Try it, and let us know what you think.

I agree. Upsampling to DSD64 is not beneficial really (to my ears anyway). However, I found that upsampling to DSD256 from Roon to a Roon Ready device is considerably better than PCM, even if my MUTEC converts it back to 192kHz at the end before it reaches the Devialet. Of course, DSD256 is not possible with the Devialet. I don't understand why they didn't include that in the upgrade when today's DACs and renderers can receive up to DSD 512 even.
