You would most likely prefer the match between the Hegel and the Sonus or the Joseph's.
The Magico's Beryillium/Diamond tweeter is going to be a bit forward with the Hegel which tends towards the clean and visceral sounding.
The combination of the clean, dynamic with excellent bass control of the Hegel works wonders with the liquid sound of the Sonus.
We would say to just go for it if you loved the sound you will already, know what you are going to get.
