hi, having been pleased with the performance of my ps3 only used for blu-ray films is it worth getting the standalone blu-ray players e.g panasonic or pioneer having been told the sound and picture quality is a lot better now than my ps3 or is it better keeping hold of my ps3.having read the recent reviews is it worth the change, i have a pioneer 436xde plasma,and onkyo sr605 reciever.
