Hi guys! Could you please suggest if this amp will be better for wharfedale evo 4.4? I have aiyima a08pro now but didn't test it yet, awaiting for my wharfedale to arrive... Meanwhile I also thought about this A70 or Topping pa 5 or pa 5 plus, but the seller told me they won't be enough and I should take pa 7... So I am a bit confused... What do you think will be the best solution? To stay on my a08pro, or to take A70 or topping?
