The sound of the unit is for the price certainly in order. Also one must not expect miracles here. Unfortunately I had with my device to already 4 times problems, so I had 3 times to send in boxes, since they had a defect in the diaphragm and very tinny sounding. Moreover, it was after 2 months, the control unit broken, so that the HDMI signal of an input was no longer flushed. The cross sections of the cables are very thin and not evidence of high quality. Unfortunately it must be said that Sony no longer is what it used to be at the site. My old DAV IS 50 was processed there much higher quality and not consisted of as much plastic as this device. Therefore, I would recommend it very limited.
