I buy this and i find it really easy to install . the music quality be awsume and it rendor the sound effect very well in movie . if i have to say anything negative about this be while the sound effect and music seem to be very well rendore the volume for the people speak in the movie seem to be really low for some reason i find myself have to adjust the volume oftem just to hear they speak . i do not know if this be just a issue with the blue ray \/ dvd but i dont have this issue much when im just watch the Satelight tv station . but over all i be happy with it a i recomend this to other buy this its worth the price you pay . oh dont forget to buy the cable you will need the Dmi and fiber optic cable for the best quality it do not come in the box . as do most sony product for some reason .
