Best amp to drive Wilson Yvette’s


I currently am looking for the right amp to pair with Wilson Yvette’s. I currently have a Pass 250.8. I think I’m looking for more headroom than what the Pass 250.8 can offer. 
I look forward to any thoughts or insights. 
Thanks.

ARC Ref 75se has plenty of power given the efficiency of the Yvettes. A very good match with no impedance issues. Wilson and ARC mate very well. A special combo imo. Most SS will not compare unless in the region of a Luxman m900u. 
How about an integrated? The ARC and Luxman integrateds are in that price range and do a pretty good job. :)


Thanks 4425. 
I guess I’m struggling why the Luxman m900u or Ref 75se would be any better and with more headroom than the Pass Labs I have now. Would love any insight. 
I appreciate the feedback!
