I dont thinknthe release date has been announced.
I was basing the release date on the pre-order shipping date in the Roon store. Last time I looked it stated a shipping date of 15th May. Just looked again, and now it says "Expected release date is 10th Jun 2024’

No date, but UK and EU are next in line
Hey @Guy_Brown and @hashkey, thank you again for your interest. Since we announced Nucleus One, we’ve gotten a lot of questions about international availability dates and costs. Please stay tuned for further details. We’ll drop updates here, via email, and on our social media platforms once everything is settled. It won’t be long!

But waiting is long…oh so long lol

Would be nice to know the specs of the CPU, guess we’ll get that once the first units are shipped and some dude does a teardown.
Anyway, I will pre-order once it is announced for the UK. I’ve got a NUC i5 (2 cores, 4 threads) and it will be a nice future-proof upgrade……

No such thing as a future proof upgrade where computers are concerned!

If you know the power you will need and can control the software, computers are quite future-proof these days

So what user has control over the software development process, which invariably requires more and more resources ?
Roon has complete control and an interest to support existing devices. Plus, as a tendency they are moving stuff into the cloud, not onto the server

Will our preorders ship May 15th?

Daniel that’s a very helpful observation. As you know I’ve dropped a lot of Tidal albums out of my Roon library because I don’t need them in my library to find them when I want to play them. I do generally keep at least one album of every artist I listen to, in my Roon/Tidal library.
But your point is well taken. As I think I’ve also mentioned I often listen to a very large jazz playlist that is now 615 tracks/56 hours. Some of those tracks are from albums in my library, but many are not. I wonder if the fact that the non-library tracks are still played quite often, influences Roon’s Valence. But I suppose there is no way for us to know.
Here is a (first?) review with pics:
Test: Roon Nucleus One – preiswerter Komplett-Musikserver - LowBeats
Roon Labs, die seit kurzer Zeit zum Samsung/Harman-Konzern gehören, kommen mit einer nächsten Genera
www-lowbeats-de.translate.goog
It seems it uses some basic 4-core Celeron CPU, 8GB RAM and 128GB of (onboard?) storage. It is def not a NUC platform, as it has different I/Os on the back panel, isn’t square etc.
The small fan used is similar to the one used in early NUCs (up to 7th gen), so it will be on the louder side when it kicks in.
Performance wise, as someone mentioned, it should benchmark somewhere between the original Nucleus and Nucleus Plus (probably closer to the regular Nucleus).
Still, looks like a great entry package, at much lower price point.

The LowBeats review was posted in this thread 26 days ago. It’s not an N100.
Absolutely a great chance for roon to attract some new consumers who are not willing to spend a fortune.
My only concern would be the fan. I guess a lot of people might want to place the Nucleus One next to their TV, loudspeakers, router or on the desk. Was really hoping for a passively cooled, completely silent unit.

As a user of a NUC (Running Roon OS originally but latterly DietPi) in the standard case, I can’t say that the presence of the fan bothers me. I don’t do upsampling/DSD conversion (or any other demanding DSP) but I do do convolution filtering and I do frequently have two zones in operation at the same time - sometimes three.
My NUC is in a well ventilated area in my lounge with the rest of the HIFI gear and never works hard and I don’t think I have ever had the fan turn on in use - not even when scanning/analysing the library (I use throttled background analysis with fast on demand analysis). If it wasn’t for the fact that the fan turns on briefly when the NUC first powers up, I might be worried that the fan wasn’t working.
Of course, if I was converting to high bit rate DSD - possibly on multiple zones - and working the Roon Server hard, I might think differently. But would I then be in the market for a device like the Nucleus One? Or would I be more likely to be thinking about a Titan, Desktop (PC or Mac) or other high performance solution?
Don´t know which NUC and case you are using, but I would assume it very much depends on the CPU and how you use roon. A powerful modern Intel core might run all things you describe without ever getting warm and needing a fan.
I run roon on a NAS with a similarly powerful Celeron CPU compared to Nucleus One and noticed it getting pretty warm when demanding computing-intense operations for an extended period of time, especially text searches, composition lists and alike. It means as much stress for the CPU as turning audio analysis on 2 or 3-core fast mode. Playing music on the other hand is never really heating things up too much, even fierce DSP, broad streams and cross-coding.
Maybe I am more concerned about this fan noise issue as I had pretty disappointing experience with a compact NAS having a similar CPU. In idle it is completely silent but after some intense operations the fan is suddenly starting to make some hissing noise. Sincerely hope fan and case of Nucleus One to be designed with more respect to that.
N100 is a more modern CPU compared to the aforementioned Celeron quad cores, offering better benchmarks in single-thread operations and it is a particularly low TDP one. x2.5 speed per zone indicates there is lots of computing power not permanently used even if you put such load on all 4 cores simultaneously.
But good to hear such affordable mini PCs can be quiet. Maybe the NAS I tried was simply too compact and too many things squeezed inside the case.
I have tried such MUSE/DSP configurations on my NUC (for the purposes of illustrating support replies) without the fan turning on ( I think, with one particularly brutal experiment I even got down to about x1.4 processing) but I don’t think I have ever run them for long enough for the server to reach thermal equilibirum under such loads - so I can’t say that my fan wouldn’t turn on in such circumstances. In fact, I would be surprised if if didn’t.
However, I have, again, to question whether someone intending to do such operations routinely, should be looking at a device like the Nucleus One - or whether they should be looking at a more powerful option.
My NUC is an NUC11TNHi7. At present it is running just one zone with convolution equalisation but the core temperatures are 25 Celcius or less and that is in a room with an ambient temperature of ~19 Celcius. So I have a lot of thermal headroom before the fan turns on when the cpu core temperatures reach 60 Celcius.
I don’t monitor the cpu utilisation or temperatures closely enough to know what happens when I do text searches (or any other search/filter operations) - but, as I said in my earlier post, I have never had the fan turn on.
