I finally got my bd 55. I got the only one in stock at my local CC. The setup was fairly easy. I set it up for 5.1 audio through analog. And with hdmi for video to my samsung 120hz lcd.
Now as for performance, I can only compare it to my ps3. And I can only give you my two cents for what its worth.
The Blu-ray video is amazing. Compared to my ps3 it seems like the black levels are better. It also seems that the colors are spot on and more natural. And the bd55 is super quiet especially compared to my ps3 which is like a hairdryer. However upconversion of stardard dvd'd seems slightly better on the ps3.
And the sound is just as good as the ps3 for regular dolby/dts.
But the true hd through analog is a little if not much better. In the street scenes of Blade Runner the true hd really shined, as I heard sounds and even bits of conversations I never heard before.
There are a few cons so far though. Although, they are in no way dealbreakers, but I should at least mention them.
The bd55 is much slower to load and play compared to the ps3.
Also the remote and on screen controls are slow/sluggish. And you can't change settings in play mode like the ps3.
Again, this is only my (two cent) opinion.
I love this player. I am extremly happy.
