I found this on the FAQ section of the Magnepan website. What do you electronics experts have to say? I know that Masa(Sushi) drives his 4 ohm Hales with an Elite vsx 45 with no problem. FYI on the Pioneer site I couldn't find a 4 ohm rating for the Eliltes, just that they recommend 8-16 ohm speakers and make accomodations for 6 ohm impedance. Is it just that Magnepan's are greedier than Hales or is this a blanket admonition?
