I saw these side-by-side today. Sadly, since I was really interested in a ws set, the KP53 just had a sharper picture with a little better color on Fox news channel on local cable. No matter how we tweeked the sets, the 53 had better detail and the 57 seemed a little soft. Could it be that the 53 has more "edge enhancement" or SVM than the ws 57"? For the purpose of this comparison, the KP57 was set to the 4:3 setting. This result surprised me because across the street at another store(that pushes Mits, BTW), they had the KP57HW40 set up next to Sharp and Mitsubishi HDTVs playing the ubiquitous HDTV loop. The Sony 57 by far had the best detail and color rendition there. Could it be that the Sony ws sets are super sharp on HDTV, but soft on an analog cable signal? I can't explain these results, but I was a little disappointed to see the 4:3 set turn out to be better since I was wanting to get a ws. The KP53HS30 does have a 16:9 mode however, so maybe that is the way to go. Has anyone else compared these sets?
