I already have a similar 2.1 amplifier. I received this one fully assembled; for the other one, I had to secure the panels with small screws between the panels, using spacers and small screws. I tried it from USB and it sounds good, the product is EXCELLENT, and I received this one on the 8th day from the order. Thank you very much for the excellent product and the fast delivery.

Looks good, the same as in the pic, sounds good. As expected. It is a bit difficult to attach the cables from the speakers using a screwdriver is required ...but that is needed only once for setup.
