WiiM has confirmed they're using the TPA3255 chip. Amir has just measured a TPA3255 amp with post-filter feedback (PFFB), which takes this chip to another level, apparently, and helps with that load dependency of the FR. @WiiM Team, any chance of implementing the PFFB?

3e audio TPA3255 Amplifier Review
This is a review and detailed measurements of the 3e audio TPA3255 chip based stereo amplifier. It was sent to me by the company as a complete unit even though they only sell the amplifier modules. As you see, it is a generic box which is something you can easily build yourself. I don't know...

For those interested in technical details of PFFB for 3255:
3E AUDIO 260-2-29A PFFB Stereo amplifier Module
The 3E Audio PFFB module is a high-performance Class D amplifier that can operate in stereo (BTL) or mono (PBTL) mode. It is based on the use of TPA3255 amplifier chips allowing it to develop an important power of 2x225W or 1x250W under 4Ω.
I've seen some measurements of this module, results were impressive.3E AUDIO 260-2-29A PFFB Stereo amplifier Module

Something to add in the Wiim Amp Pro or Amp Pro Plus.
Would be awesome if it has those mono block I have can be utilized.... and a pre-amp out

I don't know if it's just human nature but I see this in other arenas too - when a new product comes out, there are more comments about what it doesn't do or could have done better than there are comments complimenting it. Guess we're just an unhappy bunch at our core 
in principle if a small headphone module was developed it could be integrated into a streamer alone like a pro pro plus... without hp amplification, mini system etc...
True sweet chick lol human has no satisfaction in life there will always be something that they always want or need. Even they give you 6 girlfriends you still not be happyI don't know if it's just human nature but I see this in other arenas too - when a new product comes out, there are more comments about what it doesn't do or could have done better than there are comments complimenting it.

Don't forget a Phono In.... and a pre-amp out
Actually, I would love that. And an integrated CD Player. All I would need then is the WiiM Amp Ultra Mega Pro, my Lintons and my DUAL turntable.

Except that this (PFFB) is something TI published for the chip that WiiM is using. They could have implemented, but chose not to, for some reason. Perhaps it’s a couple of bucks more parts?I don't know if it's just human nature but I see this in other arenas too - when a new product comes out, there are more comments about what it doesn't do or could have done better than there are comments complimenting it.

Given the excellent performance of WiiM’s streamers which has driven sales, you’d think they’d want the best performance from their Amp, as well.

Which bigger manufacturer has already implemented PFFB with the 3255?
If PFFB implementation proves to be a selling point, it will become standard in all future amps by Aiyima, Fosi etc. And WiiM.
Is it possible to measure residual noise?
