I buy this system because it be well-priced and it have the hdmus switching that I require , with 4 hdmus input . after go through some setup , the system sound quite good . the speaker be make of wood and seem to be of good quality . however , sometimes the sound would screech loudly for a second when switch HDMI source . and pretty soon the receiver start freezing up and become unresponsive to any button press or the remote . the only way to unfreeze it be to unplug it from the wall . this be unacceptable . I have do some research and it seem to be a common problem , although I could not determine why it happen . the best I could find be that it be possibly a hdmus processing issue . I want to like this system - I have use denon before with little issue . it be also a pain in the neck to have to unplug everything , package it , and send it back . but I be still return this system and get another brand . sorry denon . on the up side , Amazon have be fantastic regard the return , as usual .
