My WiiM Pro Plus 2nd sample test

[canard]

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

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..

My view is another one and I will write it every time it comes to my mind.

 

[Brantome]

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?

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.

We'll win it hands down

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...

Yeah, I think it’s a chord c - it was just thrown in by my dealer when I bought my amp, I didn’t specifically go and buy it

It all depends on use cases. There are threads on RME forum about fully floating setups when galvanic isolation has negative consequences for some headphones.

 

[canard]

with impluse transformer in just spdif?

Guess your concern about size of coax cable might push you back towards the Plus? You might have better peace of mind knowing you’ll have one thing less to worry about despite the perceived issues raised earlier.

I thought for an "insane" use, based essentially on its better ADC..
Since I'm still deciding if take a NAD C389 with Dirac or an Yamaha RN800 with YPAO or even a Flex mini dsp to put between pre and amplifier, in order to correct some room nodes, I was thinking to put a WiiM Pro plus on "tape monitor" bus of my actual preamp and use it's analog input and output to do some PEQ corrections even on analogue inputs, like phono or other ancient stuffs. Overall volume will be still controlled by preamp and PEQ section of WiiM will correct all analogue and digital inputs. Pro plus has better ADC, so the process will start in a better way. Eventually, an external DAC could be still used, if already available...
Up on results, I will decide how to follow on.

I will get the pro and get a suitable coax cable

Btw here is a technical review of Wiim Pro from a reputable source in Greece. You can translate (since it is in Greek) : https://www.avmentor.gr/reviews/2023/wiim_pro_2.htm

Nothing about eventually sound differences, but I tried the following cables with my Pro and all fit and worked well. Not really cheap, but the WiiMs deserve good manufactured cables!
