Hi - apologies if this has been covered before but I am wanting to set up a dedicated Roon core - I currently have core on my Mac but want to have a dedicated core I will leave on.
I have around 2.5k albums and use convolution DSP - one setting only. The guidance I have read is that a Nucleus one not suitable for “heavy” DSP use. I’m not sure if use of a set of convolution filters is heavy use??My library is way below the 12k figure mentioned as requiring a more powerful core.
Would appreciate any guidance as to whether a Nucleus one would be OK/ not OK/ a bit risky? I’d rather a simple plug and play as posed to a NUC and can’t afford a Titan.
Thanks in advance.
Disclaimer: I don’t have a Nucleus One but I do use convolution filtering on PCM data streams so the below is an opinion based on indirect experience (as well as a bit of reading on these forums).
The Nucleus One will easily do convolution filtering on PCM audio streams. However, it will likely have issues doing convolution filtering on DSD streams if you want the stream to be presented to your DAC as DSD. It may well do DSD64 and DSD128 stereo, but DSD256 and above are likely beyond it. 5.1 surround sound DSD streams will push it harder as well.
If you are happy to allow the Roon Server to convert DSD to PCM, the situation improves and it may well be able to cope with any stereo DSD stream you present to it.
A “dedicated core you leave on” is any computer that is only running RoonServer you leave on 24/7. The operating system running makes no difference to it being “dedicated”.
I don’t want to hijack Charles’s thread, but… is it possible to tell Roon to leave DSD as DSD, unless I’m using MUSE in which case convert to PCM?
i.e. if I’m not using any EQ, leave it as DSD direct to the DAC?
If your device setup options are correct and you‘ve not changed MUSE sample rate conversion settings in some custom way, that should be as you hoped for.

As Wade said above.
I’m using Nucleus Rev B so I suppose a bit less potent than the new One.
No problem with convolution up to DSD128, processor is lagging with convolution for DSD256.
Cheers
