I have heard The Avanti 3 a few times in different settings. My impression is that it sounds fast and immediate, particularly in bass. Musicians sounded like they had put in extra effort in playing. Drummers seemed like a 300 pounder and hitting with all his might. It could be exciting for rock, jazz, and big band. But at the end only you can tell if it is your cup of tea.
I have not heard the Canton.
