AIYIMA A80 Stereo Amplifier & DAC Review

Unfortunately I couldn't find anything. Does anyone use it with a smart plug to power it on? Is the amp fully active after power loss or does one need to switch it back on manually?

You'll need to switch it on manually.

@Mike8040 It does go to standby after some interval. Not sure if that works with a power strip but I suspect it would since under load it consumes lots of power. It also has a 12v trigger which should work with an IoT Relay (Google it). I have another amp on a power strip and a WiiM on IoT Relay and both work like champs.

It has a soft switch so it will remain off once the power is cut. That’s pretty typical and also probably the primary use case for a power triggered device. It is simply the push of a button on the remote to fire it up.

I bought one used incl adapter. when using bluetooth after a while the sound starts cutting off and starts distorting. I am using it with elac ubr62 speakers and a 36v 6a adapter i can check other sources after my holiday.

Is this a known problem?

HHello!
I'm thinking about buying such a device. I haven't seen much experience with the built-in DAC here in the forum. Are there any of you who use it connected to a PC? I currently use a Fiio JM21 DAP connected to an Edifier MR5. If I were to switch to an Aiyima A80 with a good quality speaker, would that make a noticeable difference compared to my current setup? Obviously in terms of volume, yes, but right now I'm mainly thinking about the quality. Or, until I buy the bigger speakers, I would connect the AUX output to the Edifier MR5 and use a PC as the input. Is this a viable option? Thanks in advance for your answers!

Connected to my PC via USB, my Aiyima A80 is powering my Polk ES20 speakers perfectly.

This Aiyima A80 amp looks very interesting and has everything I need (I want an integrated DAC). The only thing I'm worried about is overheating since I read some people mention this. Now I understand overheating is a causal effect of how the amp is used/abused. I play music sometimes for sessions of 5 hours during work, followed by gaming and or watching some youtube. However, I never play my music very loud due to thin walls and close neighbours.

Would it be wise to create an impedance chart (plotting Ohms against frequencies) of my speakers before looking for a suitable power amp? And is it a good idea to make a new topic on this, because I have some more amps that I'm eyeballing right now and would like to have some advice about factors I might not have considered yet. I spend the last two months reading up on potential power amps and dove a bit into the theory of how they work and how to match systems and speakers in general but I don't feel like I've completely grasped every concept yet.

If an impedance chart is desired for such a topic, I think I can build a simple sensor with an Arduino or ESP32/8266 and plot the results into a graph but it will take some time as I don't have a dedicated frequency generator so I'll have to figure out the software side.

Class D amplifiers are very efficient and even at full power should not get hot (average power for EDM is ~50% of peak). They also have no problem driving loads with varying impedance vs frequency and are much better in this regard than class AB or class A designs
