You have a quote from Ron saying he "hammed up for dramatic effect?" And yes, I know you saw this video as I did a search and you had post it here: http://www.whatsbestforum.com/showthread.php?18680-Maggie-7-REALLY-needs-400-wpc-plus. Plenty of people here and elsewhere have attested to need for lots of power with this loudspeaker. Do you have an explanation for that?
That aside, how much power do they need in your opinion? And how did you determine that? Where the other amps you used in the power department insufficient before you got this one? Or where they all sufficient? I am looking for the kind of detail and insight that was provided in that review. Exact records used to play. Exact artifacts honed in. Changes with amps going up and down the scale. Do you have anything like this to share with us?
End of story. You MO is circular arguments with no end game. I've got other things to do. Go borrow a Magnepan and a bunch of amps, do your own tests, and make a video. Have fun.
