Soulution or CH Precision

Sure : Magico M2 or YG Sonja 2.2

Unfortunately there are no impedance v phase graphs done on either of those two speakers. So it's hard to comment what sort of amp would suit the best.
All you can do is read all the reviews of the speakers with what amps were used, and make a educated guess. Or take amp to the store to demo them.

The Solution 711 specs will drive anything as it has current to burn even at 2ohms, to me has best grunt into low impedance more than the CH1.1

Thanks for trying George.
According to my reading ( but no measurements indeed), those are not easy to drive speakers but  not the most demanding.( I don’t think they go much lower than 4ohms) I am not listening at ear splitting level and my listening distance is not too long so « raw power » is not the most critical criteria but still important for a long term purchase.
 I have been able to listen to the Soulution YG and Soulution Magico combo. For my taste it is definitely a good match ( at least with the latest Series 7 gen) . Is it « perfect » ? No it’s not ( « surnatural » dynamics sometimes, mid a bit too forward , treble not as airy and refined than some other top contenders) but definitely a combo I can live with and enjoy !
Regarding CH P ( or DAG or Dart) I can’t demo them with any Magico or YG unfortunately so it would be more a « bet ».
