I am another happy owner of the MicroRendu since about a week. I have Roon Server and HQplayer running on a Win 10 PC and utilize the MR as a NAA. This connected via USB to my Mutec which feeds my 250 via AES or Coax. Everything works fine when upsampling up to 96/24 but anything higher begins to stutter /drop.
I have the MR connected via Ethernet Cat 6 through a Net Gear Pro Safe 16 Port switch in the living room. This is connected to my Cisco SG200 in the office where my Win 10 PC and NAS resides.
When streaming from the same PC with JRiver to my Devialet, I am getting no stutter with 192/24 material. (sorry but I am one of the few where Air actually works) Also when I place my Win 10 PC in the living room and connect it directly via Mutec to the Devialet (in combination with Roon Server running on the PC), I encounter no stuttering / drops. This indicates to me that my Win 10 PC is capable of upsampling all material to 192/24 (via HQPlayer) and my network is robust enough to handle it.
Any suggestions for me as to the best way to address the problem?
Thx BB
PS: I have posted a similar thread on CA but thought someone from the Devialet crowd might have encountered similar issues ..
I have been looking into PSU's for the microRendu. In poll position currently is one of the offerings from Paul Hynes. The one I think I might go for (I'm looking at the SR5, but maybe the SR7) has two 'rails', so could also be used to replace the wall wart feeding my Ethernet switch. The thing is, this would leave me with a PSU costing £100's, powering a TP-Link switch, which cost less than £20 I think.
This seems odd! So it occurs to me that if I am going to spend the extra dosh to get power for the switch, I might as well get it configured for a half decent switch!
Any suggestions? I haven't got a clue about Ethernet switches!
EDIT: I found this, which suggests my TP-Link is fine! Although I suspect there might be something better out there??

Haha, yes it might indeed seem (or is) overkill to use such an expensive power supply to power a cheap switch but people of course do this not to improve the workings of the switch itself but to prevent using the cheap SMPS walwarts that come with them.
To be fair all PSU's, including linear ones, create noise but in general SMPS supplies are the worst. These tend to throw quite a bit of junk back into the AC and/or leak some of that noise into anything that's connected to it, so getting rid of them from/near your system can be beneficial especially if it's a low noise system already.
I agree the TPlinks are perfectly fine in doing what they have to do functionally. A not very expensive step up may be Netgear who make excellent performing, power efficient switches in metal cases. I myself have two Netgear Prosafe GS-108Ev3's, these are small and run on 12V DC. The non E versions are unmanaged. The E's are "semi-managed" as in they have a limited (compared to a professional switch) feature set.
I recall now what prompted these thoughts, it was Guillaume's system posts about the Paul Pang Ethernet switch. Looking on the 'net I can't even find where I could buy such a thing!

Intrigued by your post it occurred to me that in my two weeks of microRendu ownership I had not tried any 24/192 material. A few 24 bit tracks yes, but not 24/192. So I decided to try some of the rather small collection of 24/192 tracks that I have. Running Windows 10, Roon, wired Ethernet (cat 5), switch, fancy(ish) ethernet cable, mR, Devialet, it works absolutely perfectly. This doesn't help you much I know, maybe just adds a little more to your puzzle.

Thanks! Although what a curious looking outfit! Anyway, I think I was coming down with a bit of upgradeitis / tweakitis earlier. Ummmm, I need a PSU, ummm, the PSU can run the mR and the Ethernet switch, ummm, an expensive PSU with a £20 switch, I need a better switch..... Gradually the £500 mR that can match £5K streamers, gains 4.5k's worth of anciliaries. Looking at my Tp-Link switch, it actually looks quite decent, with metal case etc., plus it works fine! I'm feeling better now....
It is worth mentioning that I sent quite a complicated email to Paul Hynes yesterday, requesting lots of information and considering many options. He provided a very comprehensive response, he presented many options, advice, answered all my technical queries with very technical answers, clear pricing, no BS, spot on. Another company I contacted have not responded. When reading Paul Hynes response I started to think, 'this guy is getting my business'. A case of credibility, confidence in the man, and hence confidence in buying the product. I now feel no need to look any further. Good communication = sales and a deservedly thriving business. I want to give him business! I can think of other companies that really should take note the extraordinary power of sensible, technical, communication ....
Is Paul still making supplies? I thought from Antiones post that he'd moved that to another company so he could concentrate personally on design stuff? I was half tempted at the time....
Baconbrain, can't offer much advice either. 24/192 and DSD fine here but in Roon mode. Only did a couple of trials up-sampling with HQP and no dropouts there either. There are quite a few things in the chain - Roon core, HQP application, HQP NAA, plus the upswmpling processing so I'm guessing it's tricky to debug. If the networks solid gigabit, 24/192 should be problem free.
Maybe I just never found the 'sweet spot' filter but in the few 1/2hr sessions I did I couldn't tell much of a difference between any of them or between HQP and RAAT. So I abandoned. The HQP thing's lost on me - just seems really complicated. Am happier knowing I can sync zones by keeping everything Roon.

Did I ever mention that I am not a very big fan of puzzles?
Thx for the feedback and honestly this network stuff has me stumped. Sometimes it works and sometimes not. I guess someone could make a fortune if they came up with a network design which was consumer friendly and impervious to these types of issues...

That's indeed what he wrote me but he still does consulting for Paul Hynes Audio (the company that is licensed to manufacture his PSU designs), manufactures and delivers the regulator module boards for the DIY market and answers the more technical questions from customers. He might make an exception to this 'no more custom designs' now and then, I don't know of course and it doesn't matter. I'm sure he'll make sure you'll get the best solution for your use case.
I also fully agree with Confused's assessments of communicating with Paul Hynes BTW. It's a rare thing these days but he excels in it.
