the main unit have a slick , slim design . the speaker be solid look . all the need cable be include , and everything be color code and label . then I turn it on .  First , whenever power be apply , or mode -lrb- disc\/tuner\/aux -rrb- change , a disturbingly loud `` klunk '' noise be make . the unit always power up in disc mode , and will not respond for several seconds while it try to load a disc . setting -lrb- such as volume -rrb- be often lose or different when change between mode . many function be not available in all mode . for example , `` mute '' only work when play a disc . the equalizer only apply to audio cd . and so on .  i find I have to wait one or two seconds after press a button before the unit respond . if I press additional button before the unit be ready , it sometimes do not respond , or do the wrong thing .  sometimes , while change between mode -lrb- e.g. , from radio tuner to aux in -rrb- , the disc tray would eject a inch or so out of the unit , and then stop . this be especially ironic give that the eject button do not function unless you be in disc mode .  audio and video artifact -lrb- pop , click , on-screen flash , etc. -rrb- occur when navigate dvd menu .  worst of all , the unit lock up several time play dvd . the picture would corrupt , then everything would just stop . I have to unplug the unit , and then plug it back in , to get it to respond again . this happen on several different dvd , include a brand-new , just-opened disc .  i return the unit to the store . I be not expect much , but this model fail to meet even basic expectation .
