I have a new Roon Nucleus Plus and a new Wiim Pro Plus. The nucleus is plugged into the router ethernet, but the Wiim is on wifi due to housing design, but I get at least 250mbps where it lives. It seems to function without a hitch except for this upsampling glass ceiling thing.
My problem is that I can’t get Roon DSP to even show me the full range of PCM upsampling, and I like to use the higher range, 300 to 768khz. But the Roon only allows me to check up to 192. My understanding is that Wiim will play the full PCM spectrum because it is Roon Ready. Also, when you “start up” the Wiim, it makes you select your highest level of khz, which is capped at 192. Also, Roon won’t show me the upsample to DSD option anymore. My core used to be a laptop, and Roon would show me all of the options (up to 700khz, upsample to DSD, etc) and play them thru the DAC (SMSL su-9), no problem. Now that I’m using the nucleus and the wiim I can only go up to 32bit, 192. It’s good, don’t get me wrong. But where did my options go? I feel like I made a mistake in how I set up the Wiim, or maybe I don’t understand something about using the software through the nucleus as opposed to a laptop core. The Wiim app gave me the Roon Ready option, and I selected it. Does anybody have an idea about what may be happening?
The wiims are not capable of processing anything higher than 192/24 on any of their devices regardless of connection. Being Roon Ready doesn’t make a device perform more than its internal specs, I think you’re misinformed here. Why do you want to upsample it doesn’t give you more quality you can’t add what isn’t there.
You can only upsample to the devices max spec not above it in any case. Not sure why you think it would go beyond its capabilities. The Wiims max is 192/24. The DAC chip can handle more and up to 32bit but this is all negated as it will be being downsampled internally by the Wiims software as the audio chain in the Wiims firmware only supports upto 192/24bit. This isn’t shown at all in Roons signal path as the Wiim for some reason doesn’t expose its DSP chain likely it’s doing stuff they don’t want users to see.
They also falsely advertise the device as supporting 384/24 and DSD it will take it, but it will down sample it, Roon knows this side and downsamples it before hand as it’s only exposed to Roon as supporting 192/24.
Thank you for the information. There are reviews on the Wiim Pro Plus that say it does the full upsampling available because it is now “Roon Ready.” The signal path currently shows 32 bit that is being fed into my DAC. But the max it is allowing for mhz is 192. And that’s fine with me; I was just under the impression it would have a the full load of Roon upsampling possibilities once it interfaced with Roon, based upon the reviews I was reading. I like the sound of it; my concern is making sure that I have it interfaced correctly to receive all of the options that are available to me. I was concerned I had made a mistake during set-up.
I think your may have misinterpreted what they mean by full upsampling. They just mean you can upsample to the top rate the device supports which in this case is 192/24.
So even Wiim’s website says that the internal DAC plays up to 768/32. As you can see, lots of reviewers say the same. For this to work, one reviewer mentioned making sure that the fixed volume is ON and the EQ is off…within the Wiim app. I’m going to try it this weekend and report my findings.
Its doesnt the software is only capable of 192/24, what the DAC chip is capable of and what the device does are very differnet things. BluOs operate a similar way, they have overspecced DAC chips capable of much higher than their streaming platform supports to allow for its inbuilt DSP and Dirac. Wiim is the same it has inbuilt DSP that it does not have the power to do at anything higher than 192/24. It can take higher in/ but its all downsampled before it hits the DAC.
That reviewer hasnt a scooby doo what hes talking about. Disabling anything doesnt change the signal path on wiims its always going via the same audio paths, somethign turn off but its still always max of 192/24 that the dac processes. If you dont believe me go to their forums its littered with userd thinking its capabe of higher. Its just not its bad marketing. Coaxial ouput isnt capable of more than 192/24 so how is that possible?
This has nothing to do with Roon same with any application even the wiim home app.
