I think high-current amps work nicely with the Maggies, too. My speakers are the 1.6, currently being driven by an Odyssey Audio Khartago Extreme SE - it's just 110 watts, right down to 2 Ohms, but is a high-current amp. I've used the Maggies with 300/400-watt Krell, McIntosh and Bryston amps, but the panels really sing with the Khartago. More sensible price too, in the context of the Maggies' pricing!
