Roon sold to Harman. Implications?

I think Simon has forgotten more about networks than Hans Beerkan knows.

I believe this to be true. Now only if there were badges for stuff like thatā€¦ :thinking:

I started but it was 20 minutes of a rambling talking head. If there is a document you can point to I can see what he is wanting to describe.
But yes audio over networks is something many can get confused over. Been advising in engineering design workshops all day on one such activity for a massive UK clientā€¦.

Thanks :grinning:
I must never sound haughtyā€¦ but it would be useful to see summarised in an engineering prĆ©cis what some are trying to say.

Well definitely the network topic in todays online / social media world is full of misunderstandings. And I see you are gladly very much into that topic amd have a broader understanding about interaction of various elements.

Regarding Hans you might look at: https://youtu.be/ZCFvIzzMqfk?si=n79OADNsWfUVjBng
There he is also mentioning a paper by UpTone https://cdn.shopify.com/s/files/1/0660/6121/files/UpTone-J.Swenson_EtherREGEN_white_paper.pdf?v=1583429386

Never, always enjoy reading and learning from your network posts.

The M2 Mac mini arrived today and early results are very promising. Big jump in performance but weā€™ll have to see if it suffers from a steady drop in performance as the NUC did. Looking good so far though!

Poor Hans, one can only imagine his hearing is not what it was, I tell you what though if you are suffering insomnia watch one of his videos.

The UpTone doc goes into more detail of what I was explaining but when reading it you need to not conflate physical Ethernet interface clock phase noise and leakage voltages from lack of total balance in the twisted pairs, with sample jitter ā€¦ as they are different. But indeed ground plane noise from physical Ethernet interface on lesser Streamers can modulate the DAC clock through coupling.

I used to post a good white paper on this forum regularly on Ethernet physical coupled noise into devices which describes thisā€¦ it is by TI which is relevant, as Naim extensively use TI chipsetsā€¦ and here it is

Note this doesnā€™t get drawn into sample clock jitter but it illustrates how coupled interference could modulate a poorly designed DAC clock and analogue electronics through ground plane, powerline and EM couplingā€¦ but this has nothing to do with actual network dataā€¦

There is a Davaar Beta release which now has the the full Linn RAAT implementation (so now Roon ready) rather than using the previous Songcast based Roon tested implementation. Having played around with Asset for the last few days in place of Roon, and found it to be subtly better than Roon, this new release, for me, levels the playing field. Worth a try.

Iā€™ll be interested in how you get on with a few days under your belt with the M2. Iā€™m sure Roon will get to the bottom of these issues, but if you find things better with the Mac, then I may be tempted to try running the Core on my M2 Mac laptop.

At the moment itā€™s still holding the 1-2 second load time for the genre screen which is good. A lot better than the 8-40 seconds of the NUC.

When I was setting it up, it was extremely fast at scanning drives and loading tracks. Creating backups to the internal drive was very fast as well. With the NUC, there could be a combination of bugs and that the software is becoming more demanding but the fact it would get better after a reboot would suggest more software related.

Of course, the Mac version of the core is completely different app from the Roon Rock version so may not have the same bugs or quirks etc. Once I get to a week and if it hasnā€™t deteriorated then Iā€™ll feel itā€™s been a success. So far so good though!

Sounds encouraging. I had a quick look at the Roon forum and noticed another issue Iā€™m having (fixed again by a reboot) so I suspect there is still a software issue (as you say) which needs fixingā€¦

I must admit that I missed the Roon GUI during my trials with Asset and the Linn app. The seamless integration of my local and Qobuz libraries and just the way I interact with my music collection via Roon would be difficult to move on from.

Fingers crossed !

Excellent news, that would open some opportunities regarding Roon ā†” Linn streamer interface, and hopefully it will sort out some pending issues.
Thanks @james_n

Iā€™m also watching this one as Iā€™m considering an M2 Mini to run Roon

M2 MM is more than enough to run Roon Core, unless you use HQPlayer to do some exotic DSD upsampling.

It runs HQPlayer perfectly as well. I used to use a M1 version for exactly that. In fact, it was capable of creating PGGB files which is more taxing than Roon, HQPlayer plus other servers all running at the same time.

The question is not whether itā€™s powerful enough but whether the software bugs that appear to be in the Roon Rock version are also in the Mac version. So far it looks like they may not be. Just need to give it enough time to see if they reveal themselves!

Quick question, will it run hq player at dsd 512 with one of the newer filters (e.g. ASDM7ECv2)?

I hadnā€™t tried DSD with the M1. Before I can with the M2, I need to source another HQP NAA. Most likely a pi4 or something but Iā€™m hanging back until I know Iā€™ll not have any issues with Roon.

I used to use it for 768/32 and it never really troubled it at all with any of the filters.

While I believe it may be fine, you could make use of Apples generous returns policy. Thatā€™s what I was intending to do if it didnā€™t work out. At least then you could test it to an inch of itā€™s life and return to store if itā€™s not good enough!

Edit. @Ryder35 For ASDM7ECv2 you may top out at 256ā€¦ I had a Google and some say 512 others 256. As I said, best to use their returns policy to find out for sure!

Thanks for the info. I have a Mac book pro with M2 I think and hqplayer v4 It runs 512 with the lighter filters but not that one. Was not sure if it was the same for the mini

Yeah, itā€™ll not be any better than the MacBook m2 unfortunately!
