the bhk250 sterep amp is rated at 250 wpc into 8, fully doubling into 4
so based on the specs alone one would think they would have no trouble driving any of the maggies to very nice levels in any normal domestic listening enviroment
i do recall some years back when the amp first hit the market and was all the rage that there were a few people saying that the amp would shut down or go into safety mode when they pushed it hard... don’t remember if it was maggies or soundlabs or which panel speaker... iirc the conclusion at the end of that tortured discussion was that that particular unit was defective
i also recall that folks reported that the amp sounded its best when using its balanced inputs (it is a dual differential circuit amp, so that makes perfect sense)
