I have been using roon on my on my 2011 mini Mac. This has been working without issue when running using both upscaling to DSD128 and some minor EQ.
The other day I bought a nucleus with the view that I might get some more capability / better performance then I get with the mini Mac. However, I’ve been reading that the nucleus has some processor limitations when using DSP and upscaling. I am hoping that these reports are coming from people that are using the nucleus to stream simultaneously to multiple end points.
I’ve spent some time on the Internet researching this but seeking feedback from those using the nucleus in a similar way to what I’ve described above. I only ever stream to one end point at any one time and really hoping that this will work OK.
First, you won’t notice any audible difference between ANY core. Second, Roon market the difference between a Nucleus and Nucleus+ as small vs large library (>10k albums) for small vs large homes (>6 simultaneous endpoints). DSP loading is difficult to quantify, as it depends on the task, but obviously if you want DSP for 6 concurrent endpoints, you’re asking the processor for a chunk of work. Other people (myself included) never use DSP, and rarely (if ever) run more than one concurrent endpoint, so requirements are lower. Finally, you’ll get better performance from a home built NUC8i7BEH with ROCK, if you’re up to doing this. A Nucleus(+) is intended as a turnkey plug-and-play solution for those adverse to a bit of DIY, who value official support. The community is here to help, which ever path you decide!
A Nucleus will be fine for this usage requirement.
I have a ROCK server built on a NUC5i3 with 8GB and a 240GB SATA SSD, i.e. the lowest officially supported hardware configuration for ROCK and it runs flawlessly with a library of 86k tracks/6.5k albums, with a music library on a NAS, into 5 Zones/endpoints.
I also benchmarked it with EQ DSP, simultaneous upsampling & downsampling on all zones, where it performed the same as a NUC7i7.
The single thread performance of an Intel CPU has not altered much from Gen 5 to Gen 6 or Gen 7. The NUCs can’t avail of higher clock speeds due the physical cooling requirements (same with i5 & i7 CPUs that generate more heat & have to be throttled by the microcode).
Plus ROCK doesn’t need on-board WiFi or Bluetooth, nor improved GPU performance for dual head 4K displays.
I would be very surprised if your Nucleus ever has to break into a sweat
Look the bit saying combinations of dsp not being possible… which combinations? I’m pushing mine to the max and it’s working fine. Prior to getting it I was worried I would be limited but I’m not. Their statement nearly pushed me to the + model. Maybe that’s their strategy.
I think they should be clearer so people can make informed decisions. If it’s ‘certain dsp combinations while running multiple end points’ - that’s fine. Just needs to be said so people don’t get scared into spending more unnecessarily or go in a different direction and prevent roon from continuing the fine product they have. That’s my point.
I think this is as precise and as accurate as Roon can be. They can’t spell out in great specificity all combinations of DSP functions that might or might not work on a Nucleus vs Nucleus +. I think there is a return policy if you need to upgrade.
