"Narrowed" down to this list for my listening purposes, would like some input from you guys!

I have been looking for some headphones for mobile use. I am looking to pair them with some DAP with reasonable power (probably X3 or X5 when it comes out), so I would like them to be able to benefit from the extra power from the DAP, but not require so much power that the DAP is insufficient. I mostly listen to classical, so soundstage, detail and bass (quality over quantity) are most important. From reading around, here is a list that I am considering:
MDR-1R
HD 25-1 II
DT1350
SRH840
SRH940
K 545
K 550
Soundmagic HP100
Mad Dog
I have not heard any of these. Your inputs are greatly appreciated!

Beyerdynamic T51p are great for portable use and good for your taste.
HP100 are also excellent but also quite big, but portable enough.

How does the T51p compare against the DT1350?

Not heard the DT1350 unfortunately.

I see. What did you drive the T51p with?
