cleaner in terms of jitter on TosLink? Everything below 2 ns is excellent and does it matter if your DAC buffers all incoming data on SPDIF and reclocks it with its own precise FEMTO (VCXO) clock? I don’t think so… Anyone who has the mini and pro and notice a difference in sound on TosLink in his system?

I loved Chromecast Audio when I used it a few years back - but I wasn't able to get it to do gapless playbacl. Does the Wiim Pro manage to get gapless playback out of Chromecast Audio? Thanks!

Here is a quick update and first, here is how I am using WiiM Pro
Firewall Stats
Since I set up my firewall, which was like a week ago, WiiM Pro has attempted to send 590523082 Bytes of data. That's about 590 Megabytes. I did not update the firmware or use any WiiM apps during this time. I only AirPlayed to it locally via ethernet for about 1 hour daily.
And for the last 7 days, WiiM Pro made more DNS queries than my main computer MacBook Pro!!
Once again I am not saying this is good or bad, and surely these stats aren't as bad as Google and Amazon IoT devices. I am simply sharing my findings.
Besides everything I mentioned above, I am happy with my new kitchen setup. When I was using WiiM Pro only, the sound was terrible. But adding the cheap SMSL DAC made a noticeable difference.
- Not using any of the web streaming features of WiiM Pro.
- Not using any wireless features and turned off WiFi on WiiM Pro.
- Local Ethernet only
- Stream Apple Music from Macbook Pro to WiiM Pro locally via AirPlay.

Maybe wiim try continuously to send same data because not have any response from the net, Is this a possible explanetion? Any way 95% of the devices connected in our home are made in china, what we can do? Anyone ask to wiim?

True. I just disabled the Firewall rule. I'll report back in a week.
Concerns about the bit perfectness with Tidal app playback:
Any concerns about the methodology? Would like to see this tested with Wiim and Tidal Connect, not only through Chromecast protocol or Wiim apo

Maybe just leave it with communication allowed and logging enabled. I had it for few days and I've got just 3449 outgoing NEW packets.
I was doing similar tests with the local content and LMS over chromecast. Results were bit perfect except fraction of second at the beginning of the song and at the end.Concerns about the bit perfectness with Tidal app playback:

I will check it with Tidal today.
So, comparison results between chromecasted 44.1/24 content and Connect content. MQA on the WiiM has been disabled. PC app was used for chromecast, iOS app used for Connect.
It's basically bitperfect except the beginning and the end, as the WiiM adds a fade effect which is much shorter in case of chromecast.

Same software /app as Arylic (correct if wrong) I wonder how it compares to their HD board streamer dac (just as a streamer)

When playing local files, does Wiim display the different tracks from a single-file FLAC album?
So I bought the W Pro to replace my SHD as I moved from G 8030c to 8331s. Going from Coax out to Digital in on the Genelecs.
But it’s unusable as I have a massive ground loop. Are there any easy and cheap options to fix?
E.g. this https://www.audiophonics.fr/en/digi...-to-coaxial-converter-reversible-p-15796.html
Or I have to go optical out to a balanced DAC? Such as the E50 on sale now? I hate the extra boxes but I already sold the SHD.

I had a similar converter for testing from amazon and I've returned it because of its low quality, a conversion wasn't transparent.
Toslink will fix the issue if the ground loop is due to the cable connection between Pro and Genelec. An isolating transformer for coax should help too.
BTW, how do you connect unbalanced Pro to balanced Genelec?
I am using one of these (to the digital in on Genelec)
pro snake AES/EBU SPDIF Cable 3
Digital Interface Cables Length: 3 m, XLR female -> RCA male, Suitable for all RME Fireface Cards, 110 Ω, Colour: Black, Made in Germany

It seems to be AES to spdif rather than spdif to AES as it has 110 ohm impedance, not 75 ohm. No idea if it's an obstacle or not. No idea also if XLR ground pin is connected here to the RCA shield or not.I am using one of these (to the digital in on Genelec)

What about the earth grounding on the WiiM side and on the Genelec? I'm curious how the ground loop has came into being.
