My WiiM Pro Plus (+) tests

[onlyoneme]

I will listen through headphones when I have the chance but for now … Why not ? Am I wrong in my conclusion?

I cannot say whether it's wrong or not as it reflects your personal impression. I just doubt I could hear any differences using a phone speaker.

I understand your logic. However I was seeking to verify or not based on your measured thd from the three dacs. I will report back if something changes through headphones . ( I have Sennheiser hd598) but I will still use my phone as a source .

But you do know that I didn't provide any details of the external DAC used as the third device, right?

I know . But I trust that they exist and you are aware of them. Correct?

That might explain why I thought the third was different from the other two - I thought it was the mini, plus then pro but that wouldn't be logical as the mini and pro analog output should be the same or pretty similar? In order of best to worse, playing on my PC, I'd say 2,3,1 but what do I know?

I find these sorts of tests difficult tbh unless it's night and day and tend to judge the quality based on longer listening periods - if I find the sound tiresome after a while, that tells me it's not great.

Of course, differences between these devices are significant in terms of synthetic results. They can be ordered based on some criteria, for example THD for sine 1k test signal. I must admit your conclusion is impressive

So Y, Z and X is the order of your preference, right?

I will swap DACs in case of future samples if any, and also Mini can exchange with the Pro, but not both together for reasons you've pointed out.

Yeah YZX, but as I say, I don't find AB tests that easy unless there's a slap your face difference

I've spent some time with the recorded output of the Mini and the Pro Plus for one of Macy Gray songs, a session with ADI-2 and Sundaras because I do not have a high quality analog headamp. I got 14 of 16 in ABX test but there was a small 0.8 dB volume difference I was aware of.

 

[onlyoneme]

Based on the small feedback I got so far, orders are:

Z, Y, X
Y, Z, X,
Y, X, Z

Z is unpredictable

What is the purpose of the new recording? @onlyoneme

 

[onlyoneme]

My satisfaction when something can be done better than before.

Yes but you say now the differences are inaudible . If they are inaudible why we bother with all this?

 

[Brantome]

Yeah, it’s getting a bit cryptic now…

 

[onlyoneme]

Inaudible differences between samples from the first set when compared to the same ones but from the next set of files. Up to you which one to choose if you bother with all this.

 

[onlyoneme]

Yeah, it’s getting a bit cryptic now…

Why?

 

[steadyshot]

so you had a,b and c. And now you have a’, b’, c’ where a=a’ , b=b’ and c=c’ . How this changes something?

 

[Brantome]

Why?

I don‘t know if the new set are the same as the old set I.e from the same three devices, or the same three tracks recorded differently but you say the differences are inaudible. So in terms of audibility x1=x2, y1=y2, z1=z2 so what are we listening out for? Or is set 2 different music from set 1 in which case there would be an obvious audible difference. I can’t get my head round what we’ve to listen to.

They are not the same. You can download and see yourself. Difference is not audible in my opinion, just a procedure of creation has changed so the binary content has changed also. They are of the same length now. Volume level is matched a bit better. Better alignment of sample songs to each other. My satisfaction has increased due to better work I did.

Is this really something to discuss?

Ok, I think I understand now. I’ll give them a critical listen to tomorrow. Thanks
