Through AliExpress or our official website, generally slower logistics are used. Unless you buy a lot, there is generally no tax.
[QUOTE = "AIYIMA, post: 553674, member: 19745"] L'ho controllato di nuovo.
Il nostro ingegnere ha detto che la lavagna precedente era la nostra A04 originale, ma poiché il condensatore ELNA 3000uf era esaurito, abbiamo sostituito altri condensatori, ma non c'era molta differenza nelle prestazioni.
In seguito lanceremo le versioni aggiornate di A04 e A07, utilizzeremo condensatori e altri componenti migliori. [/ CITAZIONE]
@ AIYIMA
Va bene grazie! Puoi dirci come faremo a sapere quando saranno disponibili i nuovi aggiornamenti A07? come sarà riconoscibile il modello con gli upgrade, con una sigla diversa? grazie!

See earlier post which has more details. "Not included" means you're not buying a complete assembled board as shown. The shop page is quite clear about the options - none of them come with heatsink or the big reservoir caps, and the input opamps and output inductors are both optional. @brad pitt this one has PFFB, as does the one from XRK. Neither are fully assembled though. Have a look through @daniboun's earlier posts too.

Ah ok - you should sell them on Aliexpress with the LM4562 too. Most people don't know you sell them replaced but if they knew they would probably buy more amps in your Aliexpress-shop.
On the AIYIMA website you are already selling A07 with the LM4562 OP chip on board?
If A04 and A07 are not for sale yet, when do you think they will be?
Thank you

I like the thick high quality 4 layer PCB for heat dissipation and the mounted balanced outputs. I also like the bridged Mono function.
2 of them in mono might work out well.
Just the price. Price seems high compared some other TP3255 amp boards.
It's got my attention though.
I don't know enough about electronics to really analyze it. Hopefully somebody will take a look at the photos and report back if it looks worth the price.
is anybody experience with TPA3255 anti-pop function ?
Aiyima had issue about that then i am thinking to solve it with the JLE board i ordered. May be the 8 lead component near the switch of the A07 Aiyima should be a voltage supervisor ... ?

Got it from Jlester, solid board, quality components, and PFFB :

You can also contact me if you are from Europe, I have some top end boards with PFFB available.

TPA3251 Tilear V2.1 has anti Pop function
If you are looking a TPA3255 with Anti Pop this one is OK, I tested it :

For European people only, I am working with DrMordor. If you are looking for high end RTR TPA3255 amplifier, you can send me a private message.
I have tested many many TPA325X amplifiers, see my reviews on DIYaudio, this is the best board I tested.
Spec :
TPA3255 RTR
TDK-Epcos core inductors
OPA LM4562MA
Mains Caps : 6x Epcos Audio Grade
Buffer Caps : Elna Silmic II
400W SMPS LLC PSU integrated (EDT34 core)
RFI filter.
Output filter caps : TDK / WIMA
PBTL / PBL mode (full balanced / balanced)

Here is the comparison of PFFB vs Non PFFB modules after days of listening,
PFFB: Huge soundstage, will push the vocals and instruments slightly backward. Very smooth, removed some irritating / harshness sound from the regular TPA3255.
Regular Non-PFFB: Very forward sounding vocals and instruments, more like in your face sound. Because of its forward sounding nature, some might prefer this.
Both PFFB and non-PFFB are sweet sounding, very black background, almost 'wire with gain'. TPA3255 has more bass though compared to other amps.
+1
This describes exactly the difference what i am hearing between "TPA3255EVM non PFFB" and "drMordor TPA3255 with PFFB"
Enjoy...

I share this point of view but I have also noticed that PFFB brings much more power, maybe 25% more at same volume. Soundstage is really improved and the micro-details are really noticeable when listening, specially with HD Audio files it is really noticeable .

A real and well made 350W PSU is sufficient unless you push your amplifier to maximum power every day)
A LLC PSU is better as well. DrMordor LLC PSU are handcraft and can't be compared VS Chinese first priced PSU
For DrMordor 400W (600W is a peak value)
But if you want a larger PSU, no problem everything is possible with a DIY design.
