The Fosi ZA3 is a great little speaker amp! I was looking to replace an older amp unit for my bedroom, and I saw the ZA3 had really good power output, and very important for me, it had XLR inputs (along with RCA inputs), so it would slot into my system with no problems. Set-up was super easy. I plugged in the XLR inputs from my streamer, connected my speakers, and made sure to flip the switch to the XLR inputs. I’m running it in stereo currently, but it is cool to know that you can also use two ZA3 and run each in mono for more power output. In my system with a dedicated streamer and a pair of bookshelf speakers, the ZA3 works great! I’m able to get more than enough volume from the ZA3, to the point that it is definitely in “noise complaint” territory. So unless you have a pair of super power hungry speakers, this amp should be able to handle it! Very happy with my purchase, considering buying a second one so I can try running them in mono.
