Upsampling in Roon 1.3

[octaviars]

I have a win10 desktop computer which is running Roon Server, HQPlayer and AIR. Everything works fine up to 192khz and sound quality is great

Great! Have you tried using HQPlayer to upsample 44.1kHz to DSD?

Yep, I tried HQPlayer's upsampling to DSD64 today. I didn't do any critical listening yet, but generally speaking it sounds great.

I haven't been particularly impressed by Roon's upsampling features. I think the sound quality is slightly better when Roon's upsampling is set off. This is not the case with HQPlayer. HQPlayer definitely does a better job in upsampling.

Functionally the only problem that I have noticed when upsampling to DSD64 is that there seems to come a soft click/crackle sound from a left channel always when a new track begins. I think it's just because AIR 3 isn't yet officially supporting DSD64. At least this is how I understood Sébastien's message below:

Dear all,

RC 3.0.2 for windows and RC 3.0.1 for MacOs have been published.

Please post here your feedback.

Theses RCs are focussed on the white noise and sounds delivery, all others aspects are not covered yet (DSD, Screen size, etc..) but are still in progress from our side. As soon as the CORE functions are close and delivered as expected we will dive into other aspects pending.

This is the final stage before issuing the final release.

Cheers, 

Seb

The soft crack or pop between songs when you play DSD is on all inputs not just AIR or so it was when I tried USB and AES. I think it is when the MAT switches from PCM to DSD and this happens between every song even if it is two DSD songs so it seems to me.

I know there are some discusion on Roon forum regarding the quality of the up-sampling and that HQ Player is better at upsampling than Roon. I think Roon will come with more options in the up-sampling section but if they will be as good as HQ Player time will tell.

Do yoy feel that HQ Player is doing a better up-sampling than Devialet?

What filters and sample-rate do you use with your HQ Player Devialet setup?

I am curious to test HQ player in my setup

Edit: I installed HQ Player to try it is it right that the test version does mute the sound some second and then play again? Little bit hard to test it when it does like this, I dont feel like paying 150€ without a proper test period
