now that i am an official (god it feels good to say that) ML owner i have a question for the wise. i have a pair of vantages, and seeing as how the bottom is amped and they're pretty efficient, what is the minimum amount of watts you can get away with? if i wanted to buy a tube amp and still keep a good amount of headroom and occasionally kick some ac/dc when my wife isn't home, what's the minimum? cuz i have this dream of maybe someday owning a shindo amp but it puts out only 40W per channel and i'm not exactly a 'nearfield' guy...
