Hi. I have heard the D38's (I was considering buying them) at a dealers being used with audio note amps with much less power than the amp you are considering. There were no issues even with big symphony pieces.
Proac D38 owners
have just upgraded my system to accuphase A-45 amp 45 watts class A, C2410 preamp, and CDP 67 CD player, i am looking to match them with the new Proac D38R, i am a little concerned that the low output of the amp may not drive the speakers loud enough, any one who had a similar powered amp driving a D38 can comment
