if u live near the equator, forget about the 840...its an oven. 
at the moment, i am a liking the 940 veryverymuch and i think u can get it around 200bucks in the resale market.
its not accentuated upwards or downwards.. i listen to jazz orchestra vocals...no rocksssss.
so not sure if it will work for u....if u want ALOT OF BASSSS.

if u want "more" bass, my other fav can is the d2000, and i dun sit on it ..so i guess it should last me ten years before the dustmites die off.
between these two cans, the mids of the 940 is more forward...the mids of the 2000 is more "recessed"
meaning when a lady is singing she sounds furrrrrther away from u.
but they are both very clear sounding cans.
----------------
of cos the FA-003 is unbreakeable and slightly warm sounding, very involving can, i can get sucked into listening to it in a truck and fall asleep.
its inexpensive.
