Review on Nobsound Mini Bluetooth 5.0 Power Amplifier - Stereo Hi-Fi Digital Amp 2.0 Channel 50W×2 with AUX/USB/Bluetooth Input - Wireless Audio Receiver - PC Sound Card incl. Power Supply (Silver) by James Khalifa

The build and finish of this tiny amp is fantastic and exceeds my expectations for the price. I'm amazed how they managed to pack so much power and functionality into such a small device. I can't talk to BlueTooth or AUX power as I use this amp as an external USB sound card to power two Dayton bass shakers connected to my racing simulator. No drivers were required and it was incredibly easy to set up in SimHub with LPF, eliminating the need for crossovers. The power of two shakers is more than enough with a gain of 75% in the device and 75% in the software, so I'm thinking of bringing it back to 60% in the software. I will definitely be buying another of these amps if I decide to add more shakers to my setup.
