With highly transparent speakers like the Magico Mini its purely a matter of personal preference if you power it with valve or high power SS.
I owned a speaker similar to the Mini, a ML1, and drove it successfully with 2 amps - a 15W Leben and 100W SS but have heard it with 500w Arions.
The 500W Arions were the best sounding overall but the 15W Leben was still very good - a divine midrange and even rock soundeed OK - just slightly compressed. The 100W SS had more than enough power for stuff at normal levels. I would get the 100W valve amp without a second thought if that's the kind of sound you like.
Here is one of the best articles about amplifier power I know:

I actually am in a similar quandary right now. I am getting some speakers a bit similar to your Magicos built and have narrowed it down to 2 amps - an Arion 500w and a 45W valve amp. Through the valves the vocals are unbelievably real and present but with the Arions it has better grip and bass and you can reach FRIGHTENING levels if that is your wont. Its purely a matter of personal preference.
Thanks
