I love my INT250, sound great with Studio2. I wanted Pass separates but due to WAF (I can't have too many boxes sitting in the small living room) I had to simplify to one box INT250.
i have the A3s paired with Pass 260.8s and XP-22 and they are absolutely amazing. The A5s are very tempting and I have no doubt that they would sound good with the Pass INT 60/250.
