About :

In this video I decided to combine the useful with the even more useful. I tested Fosi Audio BT20A Pro (an ultra-budget amplifier for acoustics with built-in Bluetooth) and listened to six models of operational amplifiers. The amplifier itself turned out to be surprisingly not bad, and having installed operational amplifiers NE5532 (standard), TL082, AD823, OPA1612, Muses 02 and Burson V5i D there in turn, I got a different character and different sound quality each time.
