What is the going opinion now-a-days on which one offers the best sound. I have a few DVD-A and DTS disks now and they all donít seem to be that different to me. I want to start developing a collection of one type. I just found out yesterday when trying that my PS3 does not play DTS disks but my Sony DVD changer does (as well as my car's system). But my car system does not play SACD's. Seems like they all play DVD-A. Does one really offer the best quality or is that another one of those things like Blue Ray and HDDVD that people cant decide on?
