Longtime lurker and wannabe 'phile looking for help here 
So here's my dilemma:
I have a pair of AT ESW10JPNs, and am may be getting a pair LCD2s very soon. Thing is, I'm looking for a DAC that will work with both phones. This is kind of a problem as the ESW10s are low impedance and LCD2s are comparatively higher. On another note, I'm also expecting to get a laptop soon and it will house all my FLAC files.
So I have three choices.
1. Get the HM-801 and use it as a portable player and when wanting sound from my laptop, use the HM-801 as an DAC/Amp solution to power the aforementioned two headphones. Thing is the HM-801 batteries are kinda weak, I hear, and may not pull its weight in enough situations... Will the HM-801 work as a DAC/Amp solution, or just as a DAC solution? Also, can the 801 be plugged in to the AC adapter while it's being used as DAC/Amp? If not, that's a major turnoff.. 
2. Get a desktop DAC/Amp solution like the Burnson HA-160D or the DACmini and use a portable media player like the Cowon J3 while on the go.
3. Idk, convert my music to Apple Lossless, get an iPhone, and buy some Beats Solo HD/Studio/Pros and call it a day?
I kid.
Which of the options seems most logical for a soon-will-be college student with a limited budget ceiling of around $2k? Thanks.
PS The only reason I have cash to plonk is b/c I'm pooling my "mowing lawns/serving in restaurant" money for some decent hi-end audio gear.. That said I'm going to be set back for a while in terms of upgrades/finances so please recommend some option that'll last!
