24 Bit / 192 kHz SPDIF optical output issue.

[JazzBohemian]

Hello, I have purchased a Wiim Pro Plus and despite trying it on two devices that support 24 Bit / 192 kHz via the optical output, I am unable to get a 24 bit / 192 kHz output. I can only get output up to 96 kHz. When I play the 24 Bit / 192 kHz output test demo from the Wiim Pro Plus settings, I hear distorted sounds. I have tried with two different DACs and two different optical cables, but the issue persists. I read on a forum that the issue could be resolved by using a Coax output, but I don't have a Coax cable to try this. Also, if we cannot get a 192 kHz output from the optical output, why is this option available in the settings? I am awaiting your assistance. Thank you.

Because such a resolution can be achieved. I use it, for example.
If you cannot reach 192 kHz using properly working toslink cables connected to the DACs which are capable of receiving it, and it's confirmed, then probably something is wrong with the toslink output of your WiiM.

historicly ..the standard toslink was 96k...it has been bypassed in recent years (for professional standards)...but many "receivers" will not pass 192...

You can use the RCA cable that comes with the WiiM instead of the coaxial cable. Test it out.

Can you please post the model name of your DAC here?

Can you please send the model name of your DAC here?

I'm not connected to the Quad CDP-2's (optical) digital input, but it doesn't work. Also, the M2 Tech Hiface still doesn't work from the Dac's digital input. I have two separate optical cables, one is the cable that already comes out of the Wiim pro plus device, and the other is a different brand optical cable.

 

[JazzBohemian]

Would the RCA cable that comes out of the Wiim pro device be suitable instead of a coaxial cable? After all, isn't this RCA cable an analog cable intended for Line Out?

 

[JazzBohemian]

Don't stroke with a rope

Historically ..the standard toslink was 96k...has been skipped in recent years (for professional standards)...but many "buyers" will not be able to exceed 192...

I have two relatively older DACs, but both DACs can run at 24 bit / 192 kHz. For example, I have M2Tech Hiface Evo and DAC products. When I connect Hiface Evo to my computer via USB, I can output the Evo DAC from the Is2 port and get 192 kHz output from the analogue outputs. I wonder if it supports optical inputs. This is not mentioned in the product features.

I liked the reviews of the Wiim Pro Plus and bought this product. I intended to use this device only as a streamer and connect it to the Denafrips Ares 12 device via its digital outputs to use it as a source. I have ordered the Denafrips Ares 12 device but it has not arrived yet. I also ordered a good digital cable, the AudioQuest Cinnamon OptiLink Toslink High End Digital Cable 0.75m, which has not arrived yet. Only the Wiim Pro Plus has arrived so far, and I couldn't get a 192 kHz output when I tried using my old optical cable and its own optical cable to connect it to the digital input of the Quad CDP2 and separately to my M2Tech Hiface Dac. I am concerned that I will face the same issue when my new orders arrive. If I can't get a 192 kHz output, it will be a major disappointment.

The DAC of the quad CDP-2 appears to be 24/96.

You can't always get what you want, but sometimes you get what you need—and Quad, bless its cockamamie heart, is the company that gave it to me. Nah, it didn't make me one with everything; it made me one that connects to everything. Well, almost. It packed a ton of function into a CD player—with...

I think it is possible to do coaxial audio testing with RCA cables.

I'm not sure what is causing your problem but I am able to successfully stream (from Amazon Music) at 192kHz from my WiiM Pro Plus to my Audiolab 7000A Amp which has a hires DAC (ESS ES9038Q2M chip) using an old Optical cable. Hopefully your new DAC will solve the problem, if not perhaps it's a fault on your WiiM. Good luck solving it.

You'll have to try, as other said, older DACs are limited to 96kHz because that used the be considered toslink limit. Nothing to do with the WiiM. That said any difference you can perceive between 96 and 192 is likely to be placebo effect

 

[Mr Ee]

It does indeed seem that neither of your current dacs support more than 96khz on optical.
There's no harm in trying (half of) the supplied rca cable from the wiim coax digital out to your dac's coax in.
I'd fully expect the optical to work up to 192 with the denafrips.

I bet you can't wait..
Well, I know you can't, hence trying it now and being very disappointed!
Let us know how it goes.

I have the same issue with a Pro running into a Naim DAC. No go at 192/24 on the optical but fine on the Co-Ax. I originally bought the Pro as a back up to my ND5XS as Naim had been having V-Tuner issues earlier in the year. However, I'm now finding that the Pro is well up to, and if not better sounding to me, the ND5XS in streaming through the DAC. The rest of my system is NAC202, NAP250 and B&W 804s plus PSU's - mostly streaming of a Synology NAS with Minimwatch transcoding to 24/96 as required.

If the Naim ND5 XS is the DAC you connect your WiiM to, then you shouldn't be too surprised:



That's from the specs of the current model ND5 XS 2. If this model is limited to 24 bit/96 kHz then I doubt the first generation could do better.

Sorry if I wasn’t clear but I am connecting the Pro straight into the Naim nDAC which is a separate unit to the ND5XS. The specs of the nDAC are below so it should be good to handle the 192/24.

problem can be toslink... not 192k.... handle...

The Denafrips will likely be able to achieve 24/192 through optical connection. I have the Musician Draco which is a related DAC. The optical connection achieves 24/192. Unfortunately the coaxial connection between the Wiim pro and the Draco only gets up to 24/96. I was able to achieve 24/192 over coaxial with other sources to the Draco but not with the Wiim. I'd be curious to know how you get on with the Denafrips at 24/192 through the coaxial input.

I think it is possible to do coaxial audio testing with RCA cables.

When I connected the RCA cable that came with the Wiim Pro Plus as Coaxial to the M2 Tech Evo Dac, I was able to get a 192 kHz output. However, I couldn't get it with the Quad Cdp2. It is confirmed that the Quad supports up to 96 kHz. Additionally, it has become clear that there is no issue with the Wiim Pro Plus providing at least a 196 kHz output as Coaxial. Now, I am waiting for my Denafrips device to arrive. I am curious about how the performance will be when using the Wiim Pro Plus and Denafrips Ares 12 together. My Pre Amp is the Quad Qc24 with tubes, my Power Amp is the Quad 909, and my Speakers are the tower type Quad 22L2 with upgraded internal wiring using Cardas.

I'm not sure what caused your problem, but using an old Optical cable, I can successfully stream my Audiolab 7000A Amp with rental DAC (ESS ES9038Q2M chip) at 192kHz (from Amazon Music) using an old Optical cable. I hope your new DAC will solve the problem, if not, there may be a bug on your WiiM. Good luck in solving.

Thanks
