My WiiM Pro Plus 2nd sample test

[Brantome]

but again
"what do you mean by "noise"?"

it’s described as “static noise” in that thread

I don't really understand what this means...noisy dropouts, white noise? etc

 

[Brantome]

I don’t think it really matters whether it’s white noise, crackly noise or whatever - I just took it as unwanted audio like you’d get on an old fashioned analogue radio between stations.

Guess we could ask the OP to post a graph. Just joking, of course...

it's to try to understand what would be technically involved...
what if the connection fails when this noise ?

 

[onlyoneme]

I've just captured the digital audio output for both coax and toslink, with the current FW and the previous one on the Pro, 90 % limiter. All files were bit-perfect to each other, so it's either not related to a "noise" in the digital domain or something else matters.

Comparing 100% limiter with 90% also shows that no "noise" has been introduced in the digital domain.

And the same applies when connected with Ethernet port?

 

[onlyoneme]

I don't know, I tested it with WiFi.

To be honest I am torn between mxn 10 and pro plus. Of course the price is better for the pro plus and it has the PEQ but still intend to use it with coaxial and Ethernet whatever streamer I buy.

if you don't have a dac use...there's pro "no more"(and roon possibility ..some news for roon +plus? more bands for peq?)...the price gap with the cambridge becomes really important...quite to see the evolution of the new products in one or two years....

I’ve used my Pro with Ethernet and coax for almost a year in what some might class as less than ideal circumstances, very close to my cable modem/router/switch, lots of intertwining cables (power and signal), using a phone charger plugged into a domestic 6-way multi block extension, shared with power line adaptors. My Pro Plus sits on top of my Pro beside my amp but uses wifi and analog out due to lack of Ethernet and further digital ports. Despite all that, I have no issue with electrical interference, static, drop outs or any of the ills that barely a handful of people (two at most?) have recently mentioned.

Also, if you’re going to be using coax out and bypass the streamer’s own DAC, why not just go for a Pro? You could almost get three for the price of the mxn 10

I have no direct experience of the Cambridge streamer (although I did have one of their very early dacmagic boxes years ago), but I’d doubt if they have as active, helpful and knowledgeable a forum as we have here

No doubt helpful and vivid community! Thanks for your comprehensive and reassuring answer...

What I do not understand (and I did not dive deep) is why buying a Plus instead of the "old" Pro when it is intended to use it with an external DAC. Any advantage?

Maybe hidden advantage related to circuit board? I do not remember @onlyoneme testing the clock deviation of pro plus compared to pro when outputting to a non asynchronous dac as in my case.

why not...
but it won't give you a direct comparison with a pertinant constant protocol between the pro and the Cambridge

 

[canard]

My standpoint to this homeopathic measurement results and their audible consequences in items like the WiiMs should be well known.
Anyway if one takes it as a part of the hobby its fine. Nevertheless useless..
One can do whatever one wants, our little plastic boxes are fine and unbeatable in its price range. But far, far away from giving such measurement masturbation any sense.

hihi
from experience this measurement only takes a few minutes...much less time than causing it here...
nothing to mock him in any case...

ps
it's starting to become a little tiring this targeting of "measures"..without those carried out without pretension or need for recognition of onlyoneme for example..will result in some pretty bugs..so it's more to be welcomed than mocked it seems to me.. we all benefit from it..

The Plus also has a better analog input side which some may get benefit from.

See https://www.wiimhome.com/wiimpro/specs and https://www.wiimhome.com/wiimpro/overview

Guess if you later redeploy the Plus Pro, with it having a better onboard DAC you have more choices in how to re-use it.

Horses for courses

I haven't noticed any differences between the Pro and the Pro Plus in j-test when connected to miniDSP, which is the only way available to me to "estimate" clock deviations.

the digital processing seems exactly the same..
it's a bit of a shame.. they could have added in "plus " a high-performance galvanic insulation by murata ( or pulse) transformer which has been found almost everywhere for a long time now
but we can hope that it will be present at the entrance to dac...

maybe on pcb v3? I have galvanic isolation in my coax in of my dac. I would go for the pro but I am thinking to add coax cable from qed : https://www.qed.co.uk/performance-digital-audio.html. I think @Brantome has it with chord c link. I will use either this or qed or supra trico. Do all of these fit in pro? I am also thinking to use supra cat 8.1 ethernet cable: https://www.av-connection.com/?PGr=8394 .

the impluse transformers have been rather generalized for a while on the dacs..
but keeping the precaution on the source side is not stupid..
especially as their quality now, if we do not exaggerate in the resolutions is such, that even if doubled, it is not so sensitive...
