this be my first home theater system . I read the review and purchase the Koss c220 with a good idea of what to expect . the audio output be excellent ... the best my ear have ever listen to . the subwoofer have the capability to vibrate my hardwood floor and window , but I rarely keep it that loud .  the con ... the on-screen display -lrb- osd -rrb- be not very user-friendly . you just see a row of icon on the screen , and it be not obvious what they control . Scroll all the way to the right , and more mysterious icon appear . the same go for the remote . this unit definitely have a learning curve . I think Koss -lrb- or whoever design the system -rrb- use icon so the same unit could be ship to any country and not have to change the OSD depend on the language speak there . the elapsed time be display on the front of the unit , and can not be display on the screen which be unfortunate . as other have mention , the unit be a bit temperamental depend on what you want to do . you must be in the dvd mode to insert or eject a dvd . to configure the audio , you have to be in dvd mode with no dvd in the drive . to set the clock on the display , you have to be tune into one of the two a\/v tuner . I have to dig out the manual every time to figure out which mode to be in and icon to press everytime I need to configure something .  the dvd player seem overly sensitive to any scratch on dvd , cd-r , and cd-rw . the dvd player on my computer have no problem read the same cd and dvd . the speaker wire be plenty long for my small living room . the dvd unit be relatively heavy and barely slide into the shelf in my entertainment center . after use the c220 for 6 month , the CD tray need a little help go in and out . oh well , I mostly watch tv anyway . I purchase a display unit , so I do not have much money invest in it .  overall , it be a excellent starter home theater system , and now I have a good idea what to look for when I upgrade .
