What does max amperage mean compared to the damping factor or the wattage change into different loads? Seems like an easy engineering question but I don’t see it discussed very often.
If the speakers dip down into low impedance somewhere in the frequency range, then enough current is a good thing.
If it was 8 ohm from DC to daylight, then ho much current does one need?
I think that the Saunders amps are usually the “go to” with some of the Maggy range.
