hi, firstly i'm thinking about buying the pioneer 575a, or denon 1710. I have a denon 3802, and am being biast for considering the 1710. but i also have a 50" rear projection tv, and have heard that the 1710 doesn't perform to good on a large screen??. Secondly the 575a, and this may sound a silly question, but would all dvd movies sound better via the six channel inputs, rather the coaxial input?. I would really welcome anyones info on these players, What i'm looking for most of all, is which one will sound better for watching films. thanks.
