My WiiM Amp tests

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?

 
 
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 ;) 🤣
 
Does AVR on pure direct mode is nearly or no where near on stand alone preamp?
 
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...
... with a headphone section/socket

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?

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.
 
Vs frequency or vs level? Stepped sine with one channel driven but second one captured?
