the LCD-2 need a good amount of power, but nothing too crazy.
the T1 need a good amount of power too due to being 600 ohm, however, they're pretty efficient.
whichever you buy, you will need to have a decent amp for them.
the t1 very good detailed neutral headphones, but probably not the best for electronic, the LCD-2 are better for that.
the T1 do have clean treble though (detail, extended, accurate to source without any added sibilance)
but it can be fatiguing on electronic (they are very revealing headphones and poor recordings will sound bright, harsh, or grainy), not to mention the treble peak.
the LCD-2 are much more forgiving and have a sound thats better for electronic. they have a very nice bass slam and punch to them too, very tight, very clean sounding.
the Ed.8 are good too, but the LCD-2 are generally considered better overall. also i don't know how good the Ed. 8 are for longer listening sessions, i know ultrasones tend to have their own character, especially in the treble. they are good electronic phones generally though.
