By 'amp not an issue', I mean that will not be a problem for me.
The headphones currently in my possession and not in storage are...
ER4S (nearly perfect, though could be a touch more liquid),
modified isolating HD25 (liquid, but a little uneven and not super tight or resolved),
Fostex T50rp (muddy, too much midrange, not enough extension), and
Sporta Pros (glassy and hyped, but a good utility headphone).
*Since I can't make up my mind and there is insufficient tests on all these headphones in the poll, how you vote and your explaination below is very likely to have an influence on my decision.
