Great product with room for tiny improvements

The product delivers great sound, super connectivity and surprisingly much power. Would be great if there’s a power on/off button or standby after 1 hour option.

jörg fink

Hello, You have great products but I have a few suggestions: 1. When can I connect the display to other boards? 2. why are there no ID3 tags on the free internet channels? 3. After a reboot or start from standby, the last station should always start automatically I've asked this question before... and didn't get an answer... Maybe I'll get a positive answer now
Best regards
Joerg Fink

Giovanni Piemontese
Product very well engineered and realized

Only one issue at the moment: Button board don’t have any case…

Siegfried Greve
Best Service

Everything quickly and perfect delivered

Definitely wouldn't buy again

1. First you have to do the math to understand what they are advertising as output for this amp. They say 50w x 2 @ 4ohm + 100w x 1 @ 2ohm. This is 200w total MAX output (Not to be confused with RMS output). The largest power supply arylic sells doesn't even produce 100watts, so don't expect to get even half of the power output that arylic advertises with their own power supply. There is no mention of having to use a larger power supply to get their advertised power ratings anywhere on this website, by the way. Other companies are quite open about this, such as Aiyima or Fosi, which give you a detailed breakdown of how much power their amps will produce based on the voltage/amperage of the power supply. I know, more power isn't everything but Arylic is quite misleading with their advertising.
2. Customer support is pretty unhelpful for answering technical questions that they really should know. I'm not trying to do anything crazy and asked two pretty simple questions for my DIY bluetooth speaker build, but it took weeks to get any response and the response I finally got wasn't helpful at all.
3. The amp board is not sealed and audibly leaks air when the subwoofer is playing. So much for the time I spent tuning the box..
4. ACPworkbench is a really cool tool, but the instructions are garbage. I think I've figured it out enough to do what I need to, but some real instructions would have saved me loads of time.

one of the best all-in-one plate amps

Combine the TPA3116D2, 2.1 channels, and wifi/Ethernet streaming on a plate, it's a DIY dream, and perfect for a table-top all-in-one. I'm running a Dayton PS95 full-range, and a DCS165 sub. It could be a tad brighter, but that's a driver issue, which I can boost a bit in the Workbench app.

I bet a version using the TPA3255 chip would be killer.
