Yes this one ) Chinese boards are not using PFFB. You will find it only on high ends TPA32XX boards amigo
What did you say? that is too difficult make the mods? Or you have done?
I want to know if new parts are mounted on separate pcb ?
This one from Breeze is not very safe and needs internal changes to ensure it doesn’t kill you !!
The Aiyima A04 is probably the best starting point. It works well and is probably adequate for most people.
I am specifically interested in the new 3e-Audio integrated amplifier (includes power supply in the box). This to me would be the next step up unless you want to get into assembling your own amplifier from boards.
PFFB is very much for the top end. Almost no off the shelf amplifier provides this functionality today.
What do you plan to use this amplifier for ?
My 3e 3255 has all the spare provisions for the PFFB modification,but it will be very hard due to small size. J haven't......and wont....be trying to perform this task!
You say that spaces for new smd components is already provided on pcb? In this case i can let mount by a specialized laboratory
Oke, get it. So where can i find those high end boards. For serious hi-fi use at home i must have good filtering.
This amp is gonna be used to feed my Dynaudio Emit M20's, 4 ohm with 87dbl sensivity. Ofcourse, the soundstage it outputs must be better then what i get from my Yamaha Rx-v663 right now. Which is a very decent AVR, with punchy bass and overal good soundstage (for a japanese product).
So i am looking for more finesse in the mids and highs, maybe i can subscribe it better as something warmer sounding. Bass, accurate, punchy but not boomy.
Something that is up par with LINN, NAIT or REGA. If you say that isn't possible, just say it. I can look futher 😉
Send me a private message. I will help you amigo. Keep in mind that it is also a question of budget. 😉
It was a long journey to suppress plopping noise under all operational circumstances. Now that this seems to work I revised the pcb layout accordingly adding even more control circuitry.

Hi All on this thread.
I have a TPA3255 that i am v happy with.
Its a made up board from China. The 'stock standard' dark blue one.
I use a 48V 600 Watt switching PSU (Meanwell).
Would it benefit from a better PSU ? A linear PSU?
Can someone direct me to a thread . Thanks
