I bought this for its compact size and its Bluetooth connectivity to older wired speakers. The unit arrived as advertised without any power supply. I am able to find a laptop power supply 19v and 3A that works with it. So here's my feedbacks and observations after my testing: Good - the casing is some kind of metal and resembles aluminum. The body has an overall solid feel - the speaker posts are solid and have receptacles for bare speaker wires up to 14 AWG or banana plugs - the unit is compact and is less than the size of my palm so it will fit into tiny or hidden space - Bluetooth connectivity works as advertised Not So Good - the silver volume turn knob is flimsy plastic and was not secured in place. I had to push it back into the post - the per channel power is not 50 watts even when I upgraded the power supply to the maximum 24v and 5A. So don't expect earth shattering sound from it - the sound quality is just OK and the APP to control the sound has limited tonal adjustments - the volume adjustment knob is quite loose so adjusting at higher volume is not very precise In Summary - this is an inexpensive investment to bring your wired speakers back to life but don't expect the sound quality to be anything more than from a good radio - since it does not come with any power supply, that will be extra cost if you have to buy one. In that case, simply buying a good quality wireless Bluetooth speaker may get you better sound and for similar cost - I'd recommend this as a good imexpensive option if you only have tiny space to accommodate a compact Bluetooth amplifier and stationary speakers
Schnell geliefert und funktioniert einwandfrei. Bei Beschreibung sollte vermerkt werden das Netzteil extra geordert werden muss. Trotzdem immer wieder.
