I own the Sony BDP-300 which is an entry level BRP. What puzzels me is that when I listend to music it's not as good as my 9 year old Nakamichi DVD 10S. It was my impression that these BRP have superior sound quality. Is it because it's an entry level model? Do more expensive players have better sound quality. When I watch movies I really can't tell the difference. Should I upgrade my Sony? I rather have one unit that does it all. Don't have much space on my rack. If so-which one at a reasonable price?
