this system sound great and be easy to set up . I would give it 5 star if it work 100 % of the time . however , my first one have squeal and buzz happen at random time when use the digital audio input -lrb- both coaxial and rca -rrb- . there have be multiple report of this on cnet 's user review as well . it do not happen on every system , but when it do , you 'll know it . I 'll be return the system today . I 'll try one more time , but if the second one do not work , I 'll go with Sony 's equivalent even though it have one less digital audio input .
