As mentiuoned by Dinyar, Plinius typically can drive most speakers, they are also known to go very well with Totem speakers.
The old sonus fabers seem to be well matched too..
thats a coincidence !interestingly I had already suggested the very same totem forest option for another friend and they have contacted Audionote for buying that already.
... Something in between like Proac bookshelves or Dynaudio Contour or PMC are other options I suppose. Monitor Audio and Dali were not for his liking.
