My WiiM Pro Plus (+) tests

[Maurizio]

I have an impression that the Plus is slightly warmer than the Pro during its work. What's yours, @Brantome ?

Could be an effect of the vaunted AKM velvet sound?

 

[Maurizio]

Good, that's different from my pre production one which is identical to my Pro, although I've put little black feet on it while the Pro has silver

Hi @Brantome
I've lost in the big sea the link to your small feets. Could you link it again? Black and Silver please

 

[canard]

is very significantly better ..
for an all in one affordable, it is now consistent with what we can hope for a minimum of current engineering ...
but .. subjectively .. what does it give? for you?
;-)

(a measurement ap32 and imd? in analog)... and
important.. a comparison in toslink spdif in comparison with the pro? under relevant conditions?

but I have no doubt that you will bring us more measures
;-)))

I wonder how these measurements translate on listening sessions. Akm known to have solid bass and mid and roll off high.

How much does it weigh?

It's about 14.2oz (400g), 25% heavier than the WiiM Pro.

 

[adias]

Coming soon. At a moment I can tell that my sample unit has an increased space around the coax socket. And a glossy finish of the chassis.

Stay tuned

Is this a commercially available sample? Is it for sale?

could be useful to see which filter has been adopted on the side of the dac akm, see think about proposing in wiim home the choice between the different filters offered by the akm if it is possible

;-)
but onlyoneme has the resource and the rigor etc. to quickly give us the essentials of the classic analog measurements.. but also not always the case, interesting digital measurements.. thank you in advance to him.. ;-)

Thanks @Brantome
I think that these small feets could be useful for the next Pro++(with USB and so on). If, it's presumable, i buy that device when it will be on the market my only option to place it is on top of my actual Pro. That bit of air created by the little feets amidst the two i think can help to dissipate some heat. Furthermore all my devices have their feet from the factory. I should say big feet. The pro++ would be so also in pendant.
A note. I hope that they will maintain AKM chip in the Pro next to come.

As has been reported earlier, the Pro Plus will go on sale from 5th Aug

Is there a confirmed cost in the UK yet?

No confirmed costs anywhere yet, but it’s expected to be around $220 including remote

The Pro Plus seems to use fast minimum phase filter. A response:



Attenuation is very good, 48 kHz:

There is a nice explanation of reconstruction filters here:

Reconstruction Filters For Dummies • Music For The Masses

My personal experience and homework about reconstruction filters, with the hope this may be enlightening for some fellow audio enthusiast on their path to better understanding how our devices really work

[onlyoneme]

BTW it would be nice if someone provides links to some well produced public domain tracks, lossless CD quality preferably. I would use it to prepare some comparison samples for everyone, when listening impressions part begins

I knew the article cited inside the link you posted. If I'm non wrong, is interesting to note that the latter goes to different conclusions about what kind of filter to prefere, considering also that the frequency response is different from a filter to another.
I tried to choice what kind of filter is more compliant to my preferences but, aside to the little sensation that there was something different, I didn't able to say that one was better...

I'm on the very comfortable position here as I do not hear differences between filters

 

[steadyshot]

I hear differences between minimum phase and linear phase . The first one is much preferable to me . So minimum phase for me . I am not sure about the roll off .

Me too I'm thinking is conseguence of some sort of bias but in fast change from one to another filter, relatively to 44.1, the sensation of something different, in snare shot tails or acoustic guitar strumming and even female voices, is present, subtle and quite impossible to choice a winner...
