Ampapa D1 Stereo Amplifier Review

[Mnyb]

This kind of product is not easy to game , their design pretty much ensure they are very very similar or broken .

The opposite would be true for a let’s say a tube based low feedback design with no IC’s or OP-amps that depends on component tolerances and tube selection to get its best performance and its performance would still render a headless panter anyway

 

[Bleib]

Dont see the need to talk about golden samples. The performance is OK not stellar.

I am looking for a small power amp to drive 8 ohm speakers, question why would I get this when I can get the Aiyima A80 for approx. the same cost but includes a DAC, Am I missing something?

 

[PJR918BMW]

Well I just think everybody is getting spoilt these days! Look at what this thing has - 12v trigger, balanced inputs, filter, vu meters ( not sure why people like 'em - but hey ho). Issue with PFFB but honestly is anybody going to hear it? £150 in the UK. Its just ridiculously cheap?
Channel imbalance not great but I wonder if that was the channel Amir used as a spark plug?

..well I got that wrong £128! (special offer..)

I tell ya. When the Chinese have to to revalue the Yuan and if the $ keeps dropping you will look back on these prices as a gift!

would anybody else swap auto sensing for 12v trigger?

Unfortunately the Bluetooth implementation doesn't support the LDAC codec. Otherwise it would be the basis of a perfect inexpensive 2.1 bedroom system for me. All of the supported codecs (SBC/AAC/aptX/aptX-HD) prevent the listener from benefiting from the sound quality measured here.

Thank you so much for everything you do @amirm. You have brought sanity to an important part of my life. That is especially valuable in this world where "anti-social people" are increasingly marginalising truth and facts - for their benefit and at great cost to all of us.

I won't start any discussion here, but honestly you're not able to hear a difference between LDAC and a mid to high quality compression. This is another 'anti social' game played in this realm

I have owned all tpa3255 amplifier, my last is the 3e A7, which is not susceptible to opamps replacement, contrary to all tpa3255 amplifier that will sound different with different opamps....have anyone have both, which one do you preferred

opamps will NOT sound different. You can apply EQ to your liking, it is free and easy and actually makes a sonic difference

Does Op-amp Rolling Work?

When I post my last video on review of Douk A5 amplifier, I mentioned that rolling (changing) op-amp ICs in there is fruitless. I got have a dozen comments under that video in youtube asking why so I thought I experiment again with the A5. Note that I have done the same testing with both DACs...

Any idea what the input impedance is? Apparently that has become something to be concerned about (Topping I'm looking at you).

Changing opamps has been demonstrated that it does not change souding of the device

Démonstration by science, and also by thousands of people that tried and reported on forums that nothing was happening

Few, will still comments contrary on forums, the problem is that they will repeat thousands of time on several forums leading to believe that 'many' are hearing something...that is how legends starts

Numerically, yes. But it's near impossible to hear a difference between a SINAD of 90 and 100.

I'm more focused on younger ears not having the correct frequency response with the certain speakers
It does a lot right but not this part

Just dial-in "GaN Audio Power supply 52V 9A" at aliexpress.com

First hit was ^this^....
I haven't been levied any tariffs from them, to the WestCoast-USA, since Potus#47.

You can get a 48V 10A PSU for less

Both Atp-x and AAC-LC add artifacts that are quite audible. SBC comes close but still not transparent. LDAC is the only one that measures and sounds the same as the original to me. These codecs run in real-time without much buffering which severely reduces their performance compared to offline codecs (MP3 and AAC). Don't confuse the two domains.

Just an observation: This amp tests and looks almost exactly the same as the Aiyima A80. Seems like a contract manufacturer product and Douk and Aiyima are white-labeling it. The Aiyima has additional functions but the box and all the test results are basically dupes.

That does not diminish the amazing cost/performance achievement of the chipset and designer. I have the Aiyima and it is great. But it does explain, for example, the mediocre PFFB.

which touches upon what I asked which is why get the D1 when for a similar cost I can get the A80 which comes with a DAC or am I missing something

EDIT: D1 has HPF and 2 year warranty which the A80 does not

 

[Emiyanez]

I may be missing something but I do not think this amp deserve so much praise.

The WiiM Amp was launch exactly 2 years ago, has similar power, similar measurements and similar load dependency BUT it has an integrated power supply, much better connectivity (including HDMI Arc and streaming sources), much better subwoofer integration, really good software EQ, room correction and great support and community behind. I can buy it today for 75 euros more than the D1 so I honestly think it's a no brainier.

PS: As a fun note, PAPA means potato in many Spanish speaking countries. I would not be happy with my marketing team if in 2026 they could not do a quick search with Gemini to double-check whether a commercial name may sound ridiculous in other language.
