You dont need the Taobao account to buy via agent (but they will charge~ 10% more). About the shipping its a bit heavy ~400g with box i think so you could estimate 60RMB + for shipping to UK. I got the same problem. Which one of theese small amps to get

Ok, thanks for the reply Majster88.

BTW, I saw Amirm's review of Aiyima 07 which is TPA 3255 based.
He seems really impressed with how it measures.

So, I have been busy reading reviews and the Allo Volt+ D (double) seems like a good candidate.

I have the BRZHiFi PA-10 as a desktopPC powerAmp.

I just bought their BRZHiFi PA-06 (ClassD) version w/the bloated bs output power spec.
I need nothing more than ~30W/Ch for a neighbor who thinks their built-in TV speakers are good.
At $121 (includes tax + ship), I don't mind if it performs just "well' but there is no need for spectacular performance.

Just literally this morning I ordered 6 of the following:
2*50W TPA3116 Bluetooth Compatible Digital Audio Power Amp HiFi Stereo 2.0 Class D Receiver TF Card USB Amplifier Board Remote|Amplifier| - AliExpress

Reasons why I chose this over all of the others. Not much. It uses a TPS3116 which seems to be flavour of the month, it has a heatsink and output inductors (not all do) and the newer style electrolytic caps as well as supporting BlueTooth 5.
The remote control I can do without but still maybe has a use.

I'm a fan of the TPA3116, myself, but I wouldn't say it's flavour of the month. It lost that distinction 3 years ago when the TPA3255 arrived. And flavour of the month is presently drifting towards the MA12070.

Thanks for the comments guys but I think linuxfan is right here (like he always does). The MA12070 pretty much takes it.

As I’m gonna use a bookshelf speaker, it needs some power to drive it but not too much though.


Considering everything, a finished diy Allo +D is the best bet for me, right?

Or is there any amp for sale here which are designed by diyaudio members which I can use without much effort?
