this unit be very easy to set up and so far have work great . the quality be much better than I expect . I live in a apartment and it sound great in my living room . I even have to keep the woofer at half power . I suspect it be make by the same people that make oritron dvd player , as that be what my parent have and they remote be almost exactly the same , and the onscreen menu feature exactly the same graphic . it be definitly not manufacture by koss , they must outsource or license they name for it . but it still be a excellent system . I use it for the radio as well as cd playback . however every once in a while it will skip excessively with cd 's , all I do be eject it , then re-insert it and it work perfectly . my friend pioneer do exactly the same thing . no , it do not have digital input , and it may not impress you audiophile friend , but it definitely do the trick especially for the price . I look at several other dvd players\/surround sound system for around the same price and the quality be definitely not up to the level of this unit . I would recommend this to anyone not want to shell out xxx$ for a `` name-brand '' system .
