Best amp to drive Wilson Yvette’s

I'd vote ARC Ref 75SE as well. Gem of an amp and (relatively) inexpensive 

Maybe I'm totally missing something but how does the ARC Ref 75SE provide the OP with more headroom for the Wilsons than he is currently getting from his Pass 250.8?

Thanks three easy payments. I would have the same question. I moved from tubes (prima luna) to SS (pass labs) due to the fact I could not drive the speakers very loud with the prima Luna. Not sure if I could. I do like tubes, just trying to find the right pairing for the Yvette’s. 

86db with AR REf75 ?

Vitus. I have a sasha 2 vitus sia 025 combo.
Great combination.
