this unit have pretty good sound when play dvd use the build in dvd player . I even test the crossover point -lrb- ? -rrb- from the speaker to the subwoofer and I could not distinguish where the crossover point be which mean everything seem well balanced . the moment I switch to any other mode though other than the build in dvd player -lrb- radio , video1 and video2 -rrb- , I get a lot of hiss from the center and rear channel and the only way to mask out the hiss be to crank the volume way up so that the sound from the front speaker be louder than the hiss . I think I have a defective unit so I return it and get a new one and I still get the same problem .  another annoying thing about this system be that the unit itself click -lrb- not though the speaker -rrb- everytime it change track either from a dvd or audio cd . I can live with the click , but the hiss be just too much .  I be go to return my unit and get a different and quality brand , probably a kenwood or something .  I would not recommend this to anyone until classic find a way to get rid of the hiss , otherwise , this would have be a perfect unit for as I be not a audiophile .
