I have come to find that the `` Whistle '' sound in deed be true but it do not make the noise all the time . just when I first turn the system on , and the volume have to be low . otherwise when the sound be up you can not hear it even if there be no sound come out . -lrb- silence -rrb- if the system have be on for a little while , even if the volume be low , you do not hear the `` whistle '' sound . good product . good sound . for the price , you can not beat it . the option be nice . I like the fact that you can control you ipod from the receiver and see the control on you tv , just remember you do need to have composite connection to you television . otherwise if you have it connect as I first do -lrb- hdmus -rrb- you will not be able to see the ipod control on you tv . you could still listen to it , but you can not control it through the receiver . the video be crystal clear , as it should be . but even if you be not watch a blu ray , the dvd 's be still crystal clear . I will actually be get a different sound system for my live area , but this would be a good in bedroom sound and video set up . decent product , but could be better . for the price , you can not beat it !
