Born to Run: Why the Poor Sound Quality?

I have always been disappointed with the sound quality of Bruce Springsteen's Born to Run. Even the CBS 1/2 Speed Master pressing is underwhelming. Is there a good explanation for this? As I recall, Jon Landau produced the album, and he is certainly no slouch, but the recording seems inferior.

It's really a shame that there doesn't seem to be a decent pressing of this classic album
