Get the Beyer DT 770 Pro 80, got a little more meat on it's bones than the Pro 32, and while it benifits from an amp it does not need an amp
How ever, you could also look into the UE 6000, for about $115 or so dollars I think it's really wonderful headphone! And it does not need an amp what so ever :D, I enjoyed the quality of the UE 6000, and while it needs AAA batteries, it has it's own on Board Amp. Thus the UE 6000 can switch between a more balanced sound or a fun sound with MORE bass. If this is your first pair of headphones, I think you would very much enjoy the UE 6000
How ever, if you can only get the three you listed, look into getting the 80 ohm DT 770.
