I haven't heard the 7, but as a former 5a owner, these are the things that I hope the 7 would address:
Narrow sweetspot (particularly in the vertical plane)
Bass anomalies with certain recordings
Lack of midbass energy
Lack of dynamics and slam with some types of music
These are issues I had with my 5a's.
