And Chromecast (Google Cast) probably won’t work properly like with the Ultra.

It’ll be what was in the latest ultra firmware, downmixing to 2.1

So if I understand correctly, the basic difference between the WiiM amp Pro and the WiiM amp is a different DAC and that it doesn't have Airplay. Output power is the same, connections the same, design is almost the same, same functions...
As a WiiM Amp owner I`m both disappointed and pleased (that the offer is not good enough to make me want to upgrade
).
Company/product-wise - this $80 price difference is not justified and nor attractive for most users. TBH I don´t think they did a very good job with this one.

The main difference is Post Filter Feedback to make the frequency response less speaker dependent.So if I understand correctly, the basic difference between the WiiM amp Pro and the WiiM amp is a different DAC and that it doesn't have Airplay.

If I am not mistaken, the main upgrade is the improvement in sound quality and frequency response due to PFFB.So if I understand correctly, the basic difference between the WiiM amp Pro and the WiiM amp is a different DAC and that it doesn't have Airplay.

I am not sure if I can hear a difference.
See the post here where it’s stated: “The key differences between the Amp and Amp Pro include an upgraded DAC, PFFB support, the latest Wi-Fi 6E and Bluetooth 5.3 technologies, and Dolby Audio support.”So if I understand correctly, the basic difference between the WiiM amp Pro and the WiiM amp is a different DAC and that it doesn't have Airplay.

Can you please point me to a simple explanation of what PFFB is?
Don’t know if this helps: “PFFB offers many benefits including lower output noise, improved THD+N performance, improved IMD
performance, lower output impedance, frequency response less affected by load impedance, and suppression of nonlinearities of the LC filter.”

Sorry, but I doubt if I personally would be able to hear a difference.Yes, but does it sound better?
I’m happy these days to opine on features and usability of kit but at my age it would have to be a total night and day difference for me to notice
The short answer is: Yes.Yes, but does it sound better?
I don't have time for the long answer right now. I'm on holiday.

Any perceived improvement will have to be offset against the loss of AirPlay, and AirPlay wins in my case. Therefore, it looks like I won't be getting one to replace my WiiM Amp.The short answer is: Yes.

Yeah, makes me think of Oscar Wilde’s quote

Just ordered Amp Pro on Amazon this morning, gives ship date as "pending."

Class D amplifiers need to add a filter between the output stage and the speaker connectors to minimize the switching noise that is inherent to its working.
If feedback to reduce noise and distortion is applied before the filter, it is less effective and the frequency response varies if connected to 4 or 8 ohms speakers.
The better designs use the feedback after the filter (post filter feedback - PFFB) to improve this and get even lower noise and distortion.
Not sure my answer is 100% correct but should be close.
