Review: Works Good - I have been using this amplifier for a month now. It is working without any issues. The build quality of the amp as well as the adapter is very good. Looks tiny besides my old amp. My Old amp stopped working so am using this amplifier as an temporary alternative to power a set of Solidaire SS100 bookshelf speakers with a 12-inch woofer, a 4-inch midrange, and a 1-inch horn tweeter with impedance of 8 Ohms. Bluetooth range is also good. Comparable to my existing Logitech Bluetooth adapters. I have noticed it does not get warm on long usage when listening at acceptable volumes at home. The audio quality is flat and commendable in the Fosi amp, but I seem to miss the warmth my old Solidaire AS1200D amp provided. So, I tend to boost the lows and mids from the equalizer to get the desired effects. My decision on buying this over Aimyia amp was swayed because FOSI provide a warranty on their product, but Aimyia brand amps have no such mention in their listings. Review: Small on size big on sound. - Too tiny, infact the provided adapter brick is larger. Felt little warm after couple of hours of usage. Hopefully it will last for years to come. Have hooked my LG FB162 System speakers and the sound coming out is good. Even at low volume can get clarity. Bluetooth works like charm even when I take the source device in a different room still sound doesn't distort. Wish they have provided a remote or an app to control Bass and Treble. ## Features - Simple compact design but practical and powerful, little Hi-Fi Bluetooth wireless amplifier exclusively designed for the customers who pursue HiFi sound. - Bluetooth 5.0 core, up to 50ft connection range guarantees low signal delay.
