I use a variety of the offshore amps. Niles, Snap kind of stuff. If you can hear them, then you have too much power. And they sound horrible. If you can’t hear them then I doubt you need a very good amp. Can’t see wasting a Mac amp on them. Got my first set in the early nineties. Coupled with a pair of radio shack 18’s I put in a refrigerator sized enclosure. Bought them on clearance when they were phasing out raw drivers.Neighbors hated me.
