I would suggest you look at AVM. I heard the A3s at NY Audio Show driven by AVM gear in 2018 and it was spectacular. The Evoluton A5.2 would be an excellent choice. 185w and price point is $5995 without the optional DAC and Phonostage.
Full disclosure, I am an AVM dealer.
I would also think Naim, Pass, Accuphas and Luxman would all be good options. I am not sure I would try and drive those A3s with either 30 or 60w. Bass response will be mediocre with those power levels.
