I don't have direct input for you on either speaker but as a guy that's second guessing his 703 purchase what I recommend you do is spend at least an hour if not more listening to each speaker and bring a lot of different material to listen to.
What I'm finding in my case is that my speakers become unpleasing to listen to after about 4-5 songs.
