Review: Great amp - They are perfect for 2 bookshelf speakers for Bluetooth speakers and movies ! Buy it if all your looking for is movies and music Great for my house
Review: Decent sound, some design and engineering usability issues - I purchased this unit to replace an old Denon receiver and use it with an desertcart Fire Cube. I use an HDMI audio stripper to get RCA audio outputs and these are fed into the Fosi unit Aux input. I did not test the bluetooth or other inputs. Remote control functionality was the primary driver in my decision to purchase the unit. While Fosi is not a supported manufacturer for the Cube IR blaster, I was able to program the IR control using the learning function. I wish more of these tiny amplifiers would include a remote, and the one included with the Fosi unit was a decent size with real buttons. Overall the sound quality is very good, with little noise and no discernable hiss from my ceiling mounted B&W speakers even when standing directly underneath them. Unfortunately, this unit did not work for me due to some unfortunate design issues: - The remote volume control only attenuates the input signal in software - it does not change the volume level in hardware. This is not a dealbreaker since I typically use this for streaming TV and radio audio and keep the levels within a small range, but would be unacceptable if I was primarily using it for music. - The main issue: when coming out of standby (power toggle on the remote) the unit does not remember the previous input state, and always goes back to bluetooth input. Hopefully Fosi will fix these issues in future units but for now this one is going back.
