I am planning to buy the Harman/ kardon DV 31 player to complement my Harman/ kardon HK 670 amp and B & W DM 601 S3 speakers (Stereo only). I am interestd in knowing what the audio (stereo for cd playback) output of the player is like, as I am more concerned about audio cd sound than DVDs. I am presently running a Pioneer DV 355 player and do not find the stereo sound to enchanting. What is the video quality like of the DV 31? Does it have the latest features going around? Does it play DVDs of all regions, or will encounter problems on that front? Thanking you in advance...
