OK, I am a musician of over 50 years.

I have a pro-audio studio.

My audiophile listening station features Klipsch LaScala's with brand new ALK rebuilt crossovers.

My thoughts on the Prop Plus?

Well, you guessed it. There is no audible difference.

You would have thought if Wiim had gone through the trouble of releasing this upgraded product which shares the exact same exterior plastic cabinet and inputs and outputs of its "inferior" predecessor they would have upgraded the ONE thing that would be sure to upgrade the sound - the POWER supply. But, no chance. What you get is more marketing flash-in-a-pan for more $'s and the same audible sound.
 
The only difference is the DAC (and ADC).
This is well known, no one has ever claimed that the power supply or anything else has been upgraded.

Are you using the internal DAC and RCA output, in which case your conclusion is that the Pro and Plus DACs sound exactly the same, or are you using an external DAC with a digital connection from the Wiims, in which case the output will be identical?

With your experience and equipment I assume you already know this but have to ask.
 
You know, in Germany the following is common:
Die Abk. einer Abk. ist Abk.! 😉
Lol.
I'm not sure how many German speakers would know was ist die Abkürzung für das Wort Abkürzung?
English speakers either for that matter but apparently it exists.

The Abbr. of Abbr. is Abbr.!

I was hoping for the ability to play DSD files, and that’s why I upgraded. It’s silly - they should enable the ability to handle DSF and DFF files and it would be a true gem!
 
At the risk of being shouted down I think I am correct in saying it will play DSD if you use the inbuilt Squeezelite client in conjunction with LMS.
 
Well Amir in ASR would disagree! Look at the charts and numbers! We all know true audiophiles listen with their eyes. :eek:
 
The Pro+ has 25 dB greater sinad. So I would assume there could be other factors. What is the configuration of the other equipment that you have between the Pro+ and the speakers? Pre-amp? Power amp? The sound will also be dependent on the source music. MP3 and lower formats sound lossy, as their technical names imply, on any system.
 
Appears bsacco35's OP was just a Drive-By Flame-job (and a Flex on his Speakers)...

The bottleneck for both WiiM models are the power supply.
No big fault, and only relevant if the best sound regardless of price is on the table.
That is my opinion.

You can change the powersupply with a better LPS - it will sound slightly better but not as good as using a really good sounding external dac .

It’s because all (good) DACs sound the same.

So there’s some in depth measurements made by contributors to Audio Science review:

Review 1 (with comparison to Wiim Pro)

Review 2

But was your comparison a proper Blind test?

Sighted tests are almost guaranteed to be determined by bias.
 
This where this can get out off hand as this is subjective. Everyone hearing is different and so the translation on brain. The only way this to be not bias would be measurement. Remember, music is personal thing you listen to it how you like it including tweaking eq on your liking.
 
The difference between pro and pro plus is the improved dac section. If you don't use the analogue out you won't hear a difference. Or maybe just on a very revealing system because the plus is also supposed to have a better clock. So Pro to Pro plus is only an upgrade when you are using the analogue out. If you don't hear a difference there, you should look a the rest of your system first, because obviously it is the bottleneck.
