I have an NexxTech Home Theater System (ESDVD100), a nice little home theatre for the price.....I am having problems whenever I switch to DTS, there seems to be this psst air click in the front surround speaker, and if I switch and up the bass and up the volume of the subwoofer individually, it becomes worse...I am not sure if this is something common with DTS......I could have a problem with my DTS decoder and may need to get another unit, which Circuit City would replace.....ANy help is appreciated
