    The amplifier came in a crumpled package, in principle, nothing terrible. The whole thing itself, the Assembly is not bad. When you check it turned out that 2 channels do not work. The sound is not the best. I checked on decent columns. In 120 watt description, actually maximum 100 in description on the box. I have 50 watts pioneer plays better than this amplifier

    Mounting contacts is not convenient

    While it seems that everything works normally, of course there is not so much Wat.
