it perform well when I play video game use PS3 but fall short of my expectation when I play Blu Ray movie or regular cd . in those instance I do not feel the `` surround '' sound much , and certainly not from the cd . when I call Bose customer service , it be explain to I that regular cd do not produce surround sound and most movie -lrb- even Blu Ray -rrb- do not also fully utilize the surround feature . honestly I be not sure if I buy into that . I buy it because I be not a audio expert but my sense of hearing can tell what be good sound and what be not . in addition , when I hook up the ps2 through this unit use red\/white\/yellow cable , the output screen size be funky with my hdtv . so I end up bypass this with my ps2 . then there be not analog cable input for I to hook up my direct tv in to this unit so it be also a waste on that . for such limited use , I do question the value of spend $ 1800 on this . by the way , when I research different home theater system , I be shock to find many 4\/5 star review on unit that be $ 200-500 range . when I go to the retail store to test hear they , they be nothing but just louder noise . so from that perspective , bose 's unit 's sound quality be definitely crisp and very clear , but just do not give the full `` surround '' feel that I would expect as in a movie theater unless I turn the volume to be very loud .
