Mario:
Pass xa30.5 runs 30 watts class a & 120-130 watts ab
plenty of power for 87 db efficiency speakers
I have Revel Ultima2 Studios running & sound great & will run 90 db loud, nicely
I have run Thiels at 87 db efficiency , too
most of the time the class a meter never moves (30 watts) and never goes out of class a
lovely amp
I think any moderately efficient speakers above 87 will work
