This is a great mini amp with amazing sound, which I believe is due to the TDA7498E chip, which delivers high power and clear, undistorted stereo sound. The CSR64215 Bluetooth chip really helps achieve faster and more stable transmission. I compared this amp to the Fosi BT20A and the difference in performance was significant. The Fosi amp was much smaller in size and weight with the same build quality. Fosi's power supply is 24V 4.5A while Nobsound uses 35V 5.0A for 80W per channel for my 8 ohm AR speakers with a passive subwoofer. I immediately noticed that the sound of the Fosi is not as powerful or transparent and clear as that of the A2. Fosi uses the TPA3116 IC with 0.5% THD and 88dB S/N versus Nobsound's 0.01% and 98dB S/N. I found the Fosi sound tiresome no matter how much I maxed out the treble, bass and volume on all devices, and still sounded thin with confusing channel separation. I only gave Nobsound 4 stars because you have to switch it manually if you need Bluetooth, not Fosi who switches it automatically! This is a huge benefit when switching between listening to music from your device and streaming audio from your TV to your speakers! Second, they placed the switch on the back of the device, making it difficult to reach and impractical. Otherwise, the Nobsound A2 was perfect for my audio enjoyment!
