Fosi Audio BL20C, 320 Watts Bluetooth 5.0 Micro Stereo Receiver/Player Amplifier $130.79 Delivered @ Amazon AU

Public service rather than a "deal" per say. Yes, you get $22 off the normal price, but it's been going on for a while.

Still, not bad at just over $130 for a fully functional bluetooth receiver, USB player and amplifier. All in a very compact form factor.

So if you want something to drive a set of some speakers you have sitting around without blowing the budget and taking a lot of space, this is pretty reasonable.

I ordered two to drive built-in speakers I have around the house and can report they are marvelous little things.

Sound quality wise… Well, I used to have my old Rotel plugged in. It did sound better. But I was told to get rid of it - big and bulky. So on the balance of no sound at all and sound from this thing, yes, vast improvement. There are threads in the wild suggesting more powerful PSU - apparently will sound better. The way it comes is not going to get your neighbors rocking but is perfect for some background music.
