Monitor Speaker pairing for Leben 300


Hi there all,
Just looking for suggestions on monitor speakers efficient enough to be driven by the 15 watt Leben. If anyone has direct experience or suggestions that would be greatly appreciated.

Thanks

I have a Leben 300XS, driving Harbeth C7ES3's. My room is 12x12x9, and I listen to jazz and classical at moderate levels with excellent results.
Very happy with Proac 1SC for two years. Had Audio Note AN J earlier, not a monitor strictly speaking but also superb match. Swapped due to the foam surrounds (and wifie, they were black). 3,5x 5 meters room, all genres.
