Ask your friendly work tech support if its possible to run portable applications off of a USB stick or if they have that disabled. if they dont, you will easily be able to plug your DAC in to your work laptop and plug your USB drive into your computer. the usb drive will have all of your music and this little gem on it: http://www.portablefreeware.com/?id=184
if your DAC is plug and play, you will be able to use it that easily. Worst case scenario you may need to change the output device on your computer, and thats generally not an admin only privelage. if it is, screw microsoft.
EDIT:
I saw that meet and it sucks but the timing is horrible. I'd really like to go with my girlfriend because my parents dont trust me to be off alone (long story). Not to mention, I have only my laptop and A5's on hand instead of my turbines and my Y1/Y2 (which is in repair in kalamazoo
) I'll post there though so i know about any future meet ups. I've been wanting to check out various on ear headphones because thats my next large purchase aside from an arduino and some electronics stuff. I had her listen to my monster turbines and she was taken aback. They've been in warranty repair since then so I havent quite gotten her to convert to the audiophile side. She has a very 7th grader taste in music (3000 songs, 2980 artists, 2990 albums) but she does appreciate good vocals, especially female vocals. And corny, testicle scrunching lyrics. Right now her music is in an abysmal state, and if you are a true audiophile this might make you vomit: itunes 128kbps m4a converted to 320kbps mp3, put on a google Nexus S completely unorganized without any tags pointing to the correct song, and she's listening to this all through the plastic bundled headphones that came WITH HER PHONE. It would be amazing to show her some proper equipment and have her listen to, say, B&W 800 diamonds out of a proper dac, powered by McIntosh pure class A tube amps.
