I just bought the new d3020 . I currently have it driving a pair of Proac response 2.5 floorstanders in a small room. I have to say I am very impressed with this amp. I can go to the volume I desire and the bass is impactful ,highs are perfect tonally to me. I bought it to use for listening to tv and movies but enjoy spinning discs in the room too. The proacs sensitivity is in the low 80's ,probably similar to the maggies . The right size room would be the main factor for it driving any speaker .
