I sgree with u..plNrs need some headroom of extra power..BUT..maybe its better to say they need QUALITY power..not just raw power..and no matter the power it has..if it doesnt synergize with the phone u have it doesnt matter how powerfull it is..synergy is the secret ingredient..
like he 500 is perfect with 337
but 337 not so with lcd 2 and 3
but lcd 2/3 do perfectly with v200
hd800 is horrible with 337 ( i actually bought my amp from a newly owner of ahd800)
but bada amp does perfectly with the hd800
and so the list can go on and on and on..
