The funnily thing is that the power adapter has almost the same size as the amp.
The chassis is strong enough, and the usage is very intuitive and quite brilliant effort at simplicity by SMSL engineers.
There is a large dial on the front panel of SMSL AD18. It is an all-in-one button for multiple usage, volume control, power on/off and menu selection.
Besides, AD18 comes with a aluminum remote, and it is pretty small, only half size of a credit card . All functions can be controlled by the remote, and again, it is very intuitive.
PS: for transport security reasons, the battery was not installed in the remote, so you need to install them before operation.

Sound of SMSL AD18
The sound is amazing, great bass and a nice warm quality. The 80Wx2 power rating might be a little optimistic, but it DOES seem to hold its own against a 60w Yamaha A-S301.
When I connected to its Bluetooth for iPhone streaming, the sound was very clear and free from any kind of distortion. The reception and range of its Bluetooth is impressive. I can walk across my whole house while maintaining a stable connection
I used my headphones to listen and the built-in headphone amp works great too. Then when I switched to speakers, the sound was again very much engaging.
In short, all the inputs works as expected, except the aux, so, if you generally rely on analog sources, AD18 might not be the best choice for you.
The good thing is that there is a subwoofer output for SMSL AD18, so that you can drive your small bookshelf speakers plenty loudly.
