For example, when using line in mode, you can control the volume by attenuating the input signal (changing the volume on the source device). However, when in bluetooth, the source level is kept fixed, so the only way to adjust the volume is to physically walk up to the unit and turn the knob. And there's no remote, despite how cheap this would be today.
Worse, when in bluetooth mode, the volume knob doesn't have the full range. Below a certain point, the volume cuts off completely, despite the fact that it's still fairly loud and I'd like it to be quieter. Can't adjust it on the source, that level is fixed until a certain point, at which point it, too, drops out all at once.
If I could only adjust the source level for bluetooth, I could set the volume knob somewhere appropriate for the situation, and fine tune with the source volume control (i.e. my phone). Instead, I don't have the range of control I'd want _at all_.
Also, this device is super eager to pair in bluetooth, regardless of what mode it's in. It can be in line-in mode, happily playing away, and then I come home and my phone automatically pairs, and starts steaming all the phone's audio to speakers which I didn't want to use and which aren't even switched to that source! The only way to "correct" this is to turn off bluetooth on my phone, or manually unpair (which requires re-pairing next time I want to use it).
Finally, when it is in bluetooth mode and playing sound, I have found literally NO way to switch back to line-in mode other than physically power-cycling the device. This isn't hugely inconvenient since there's no remote anyway, but it's a highly unintuitive UI design.
Audio quality gets no comment as the UI design is far too frustrating.
The Lavaudio has a metal chassis instead of a plastic one and that could shield it better from interference.

Bad for BT headphones too, because the BT is receive only, not transmit.
Misinformation. Like most bluetooth connections to a phone, you can easily adjust the source volume when connected via bluetooth using your phones volume control. This is the way most bluetooth headsets operate.
I have the mii version of this amp for our speakers outside. It's been great.
All of the ui frustrations listed are related to not using the device as intended. Granted it could be a little more flexible but it does a good job of what it was meant for.

if you want to use headphones you can get that product for much cheaper!

They are both metal bro (I have the other one). And you aren't going to get any interference improvement even if it was plastic. Noise levels are going to be driven by PSSR, amplifier design and pcb layout. Not RF interference. you could pull the case off the pcb and it would perform the same. shielding come primarily from the near field proxima of ground planes in the pcb not from the chassis.

If they are nuts, the FCCl:ID internal photos clearly show the plastic case. [fccid.io] Unshielded plastic cases (there is no shielding evident in the photos) are more prone to interference than metal chassis.
