I agree that simply passing through is possible. But if you can do the numbers from a Roon core perspective you also need to be able to transcode to DSD1024/PCM1536 if desired I would have thought. It is that I suspect a Nucleus+ rev. B can’t do.
Actual playback from a local WAV file is no challenge either. Can also do that even on a raspberry pi. Compute power is absolutely not the limit as even just the most basic of DSD modulators that Roon runs requires orders of magnitude more compute power.
Though even if it were the limit, restricting features available in roon because the Nucleus itself cannot handle something would be silly given as the majority of Roon users don’t use one.

I too would like to add my voice to request this feature please. I have a growing library of upsampled PGGB music and would like to continue to be able to use Roon for it.

I strongly support this feature, and have added my vote.
@GoldenSound, since the motivation for this feature is software upsampling tools like PGGB and HQPlayer Pro, have you also noticed that 48k DSDxxx files created by HQP Pro are also not recognized by Roon, even though many DACs are capable of playing them?

I agree with this feature. roon should be a thought leader for ultra high res audio.

Agreed - I hope Roon adds this feature.

+1. I’ve got a Holo May and I’d love to have Roon be able to play these ultra-high resolution files (32fs+, DSD1024+).

And also x48 family! Currently Roon only supports x44.1 on DSD, while May would have support for both.

+1 on 1.536 PCM / DSD1024 and 48k family.

A kind reminder that this problem still exists.
A very long-time original life-time license owner of Roon here. Just got a Spring 3 DAC and was very surprised and disappointed to find that Roon doesn’t support these higher bit rates - and quite frankly it looks like it never will

Bump for support
Did you vote for it @Johnseye? That’s the only action that Roon will pay attention to. The bump might get others interested, but without votes it’s goes nowhere.
Yes, I voted for it.
How difficult could it be to support those frequencies?
