Which Class-D amp to get from Aliexpress?

Seems like using this board as a dual mono TPA3221 at $26/each is kind of like the upgrade for the old Allo Volt+D dual mono TPA3118 board.

Wondom shop launched a Bluetooth amplifier, I2S TAS5768 2x50W, seems to have HDMI audio extraction function. Have you tried it?

Officially the weirdest Chinese amplifier I've ever laid my eyes on 🙂

🤣 I found the introduction video on their youtube channel.

Now that I've seen it in action it's not all bad. Some of my thoughts:

• USB-C for power input (Type-C chargers are cheap and can be found everywhere). Having a 5V-2.4A normal USB out for DAC or other devices is also neat.
• HDMI in and out.
• Speaker jacks. Although I hate it, I understand it's due to a lack of space.
• BT connectivity is alright (no JL Chinese specials).
• No analog input whatsoever?

In conclusion, as someone who uses a laptop setup, I can totally see myself using this product as an "audio-video hub" (AV hub for short 🙂). All I have to do is to connect a HDMI cable to get good audio and video output simultaneously.

Does this look like a new batch of the TPA3221 mono amps? The originals are quite expensive now.

Go to the "coins" option and you always have a discount of a couple of euros(sometimes there is a discount of 15-20e)

Shipping is free for the USA, but not for other countries, the price difference for me was about 30e

 

[jgaupel]

So they charge you more to ship the FOSI!!! I was talking about the difference of price. I hate that my fellow audio hobbyist get hit with higher shipping even though they may be much closer to the product origin. I suppose it has to due with product warehousing locations or just shear amount of imports to the US.
