ARC Ref 3 good match with pass Xa 250.5

Looking for feedback on these units match together.
thanks mike
If you are running them balanced, then from an impedance and sensitivity matching standpoint there should be no issues.
Those will work great together.
What is an XA 250.5?
That would be a Pass Labs XA 250.5 power amp I believe.
What Peterayer is saying in his Socratic method is that there is not an XA-250.5 model. There's an XA-200.5 model and an X-250.5.

In each case, there should be no matching issues.
