Hi I want to replace my pioneer dv656 with one of the above. Not concerned about the feature list - I know the differences in spec from the reviews and this forum and that the 900 has a hard drive etc. What is important to me is normal dvd playback - Picture and sound quality.i.e I will buy the 900 if picture and sound quality are better regardless of a hard drive or not. Anyone know how these compare to the DV656 for dvd and cd playback and the big question is: Although the video specs (Dacs) look the same in the spec , does the gx700 have better sound stages than the GX300 and the hx 900 better than the gx700 or is the picture and sound quality trhe same with only the features different. Final question please, does the rdr gx7 (earlier model) have PAL progressive scan out. Thanks for any info as its hard to demo these players anywhere.
