Hello, since there is no real Roon Support here in Germany after Roon was sold to Harman, I have a question I hope you can answer, nobody in Germany can. I have Active speakers from the German brand Phonar, which are connected to each other and to a Platin Hub via Wisa. The Platin Hub is Roon ready, it is connected to my Roon Core, which is a ZenMini by Innuos, via USB. The ZenMini is connected to my Home Network via LAN Cable. This Wireless Connection works with 96kh, if I stream with native Qobuz over the Hub, it works with 96kh. The Hub can not do more than 96kh, but thats fine. If I stream with Roon over the Platin Hub, which is recognized by Roon as Roon ready, I can only stream with 48kh, so the system does a downsampling which I dont want! So right now the Qobuz App ist better for me than Roon, because it works with 96kh, and Roon only with 48kh! I cant change that, I have tried everything! But I normally prefer Roon over the Qobuz App, and I would Like to stream with Roon in 96! I already have changed the maximum sampling rate to 96 in the advanced options, but in the end, when I look at the signal path, Roon always samples down to 48. This obviously is a Problem with Roon, not with the Platin Hub. Can You please help me? Thank You!
Describe your network setup
My Router is a FRITZ!Box (in Germany), my Roon Core is a ZenMini MK3, my Roon endpoint is a Platin Hub.
It’s as expected and as explained in the older thread I linked. You can find a detailed discussion there.
The signal path shows the linear progression of the data stream and how it moves from stage to stage. Roon hands it over to the device and everything that happens after this is done in the device; Roon only reports what the device tells it about what is happening in the device.
I have exactly the same Platin Hub / Buchardt A500 combo and my experience has been extensively cited in the referenced “solution” post.
However, re-reading that thread after all this time I can see it was left rather unresolved and never got to the root causes so I can update.
The reason for the extensive discussion was that my experience was that the roon certified Platin Hub over RAAT sounded distinctly and very noticeably “off” compared with the roon uncertified version over Chromecast, at least in combination with the A500. Initially the finger was pointing at the unexpected Platin down sampling. Subsequent to that thread from some time ago I eventually traced the problem to interaction effects of any combination of roon / Platin DSP. It is better to use one or the other. Rather than Platin downsampling causing a problem it is actually roon upsampling. So I switched off roon power of 2 upsampling, convolution and PEQ and used only the Platin DSP. The most noticeable effect by far was eliminating any roon 44.1 power of 2 upsampling (e.g. to 88.2). The effect isn’t subtle. Upsampling red-book to SACD sounds quite bad with this system that wants to work at 48khz or 96khz.
The reason BTW for my extensive use of DSP is the difficult acoustic environment at the location for this secondary system which practically I really cannot do anything about except DSP. It was the main motivation for choosing the DSP flexibility of the Platin/A500 combination in the first place.
I mention all this as it may help the OP look elsewhere than the unexpected down-sampling to optimise his system. There are also “master-tunings” available for download and voicing which I have found very useful. I will say though that although the SQ is now vastly improved in most cases, there are still problem areas. For example, Harp/String concertos have a poor balance compared to my main system and there remains a persistent “thump” on sampling rate changes about which I am in correspondence with Buchardt. So there is still work to do. I remain surprised that none of this seems to have been caught during the roon certification process.
