I bought it in March 20 if I remember correctly. I wanted a small-sized amplifier, but not with limited capabilities. I chose this one and I didn't regret it at all. I have connected it (periodically) to almost all the audio devices in my house. Eventually, it stayed in the office to play from the computer & the raspberry and of course via BT from all my devices. It plays with a pair of Indiana Line DJ204 & Crystal Audio 12R' sub (of the main system, but it has two inputs). The only thing I would like to know is the cutoff frequency on the sub out of the Ampster, because I have to limit it from the sub...
P.S. I would easily buy another model of Ampster III BT&wifi :-)

I had my eye on this amplifier for a while now (since the first model released by the company) as all the reviews I had read gave it an excellent performance-to-price ratio. I bought it straight away when it went on sale and after continuous use since then, I am thrilled with both its usability and its sound.
