How good is the Pioneer DVS303. In particular is vocal sound as good as Sony 550. Some systems are trebly and harsh but I prefer a more mellow vocal sound. Can you adjust Bass & Treble or is it preset. Does it play DVD+R's. Generally how does it look & sound. How does DPL2 perform. I rejected the Sony 550 due to a thin (1mm line) present at the top of widescreen movies (with black borders). That was very irritating. Any views willl be most welcome.
