I ran all three as requested, including '-loglevel debug'. All three resulting files resulted in poor quality audio as before. the filtergraph output does show something different however, but the resulting audio is still terrible and indistinguishable from before.

I do appreciate your help in resolving this issue.
Just to see if it wasn't my system causing the issue I loaded up a windows XP vm and used the 32-bit windows binary from the ffmpeg homepage, resulting in the same outputs.
