O-Noorus D3 PRO - A new TPA3255 PFFB amplifier with DAC

Done! Thank you @Alexander Lin !
I don't buy blind usually but from what I have read of other o-noorus products I am feeling confident the D3 Pro will deliver on its promises.
The measurements shared, the components used, feature set and the legibility of the display tick áll my boxes.
The amount of power on tap in 4ohm should ensure my Kef Q1 Meta speakers which succeed my current Q100 will not feel shortchanged either.
Looking forward to receiving my D3 Pro!
 
D3 PRO No high-pass filter。
With the amount of power on thap I feel this is less of an issue for most. It would have been a nice bonus resulting in a cleaner sound ( as I do run a subwoofer here though not all of the time ) but it did not stop me from ordering a D3 Pro this morning.

On a lower power amps it should be a standard imho and would have buyers much happier with their purchase which would reflect positively on any brand that offers this experience.

Some background information I found interesting on the implemented DAC in the D3 Pro

I am very excited to hear the impressions and experiences of the first users.
I am still very satisfied with my D1.
Apart from the transparent sound, I particularly like the display and the remote control.
Two things that were rather unimportant to me when I bought it, but which are really very practical in everyday use.

I'll be sure to post mine here, perhaps include a video detailing the user interface experience.
Yes with kid and cat a remote is a gift from the gods, and a display that one can make sense of at a distance makes me feel young again.
 
It's probably the next version of 4493s in this one...

AKM has been back in production since 2022. The top chip from current production is the AK4499EX.
 
Darnit now I want that in the D3 Pro! lol.. Ah well XD


*for those so inclided to want to know stuff there is more info onthese AKM in the ASR forum thread I posted above the yt video link*
 
Thanks for the pictures. I see flat coil inductors, which is a good development. I look forward to receiving the sample you're supposed to send me for testing. I also hope the ASR test can confirm the correct implementation of the PFFB circuit, particularly regarding load dependence.
 
Hi daniboun ;)

You're very lucky to have received a sample to test :cool:

(you could have given Alexander a 'thumbs up'...)
