George’s arguments are irrational. For him doubling down power is more important that the absolute power and current the amplifier actually gives.
Sorry but this is wrong, have you ever listened to a pair 25w Mark Levinson ML2’s on a pair of hard to drive speaker like the OP’s? "to a given level" (because they are only 25w after all) they will annihilate any 500w or 1000w Class-D.
This proves that doubling down (current) to below 2ohms into this kind of speaker load is the most important factor for sound quality, not wattage!. ( otherwise we would all own $400 3000W! Behringer NX3000 Class-D’s )
Although if you want to go louder then wattage becomes a factor also, so then the same kind of amp that can double with more watts is needed then.
So you my friend are the irrational one not me.
BTW You’ll never see a pair of ML2’s for sale used as owners die with them!
