Gift for the father of a friend whose old one had burned out and is emotionally attached to lamps. He was incredibly pleased.
P.S.: In no case is it suitable for professional use, studio, etc.
However, it offers a very nice touch and decor to a home.

Bad device. The sound is poor and weak, but at this price it is somewhat expected. The Bluetooth function worked smoothly only during the first few days. Afterwards, it has interruptions every approximately 3 minutes. It was tested with at least 3 different sources (mobile, tablet, laptop), while the same sources were tested in the same space with various other audio playback devices (from very cheap to quite expensive) to exclude the possibility that the sources are problematic and they worked perfectly. In other words, this specific amplifier does not work properly, at least in terms of Bluetooth, and this happened just a few days after the purchase. The customer service does not recognize the problem, insisting that it is a problem of interference in the space. In short, find something else.

It's a fake, it only has a good pre-amplifier and a final transistor, but both the pre-amplifier and the tubes are just for show, they don't do anything, only for Christmas tree decoration.
