For daily commuting/school/misc, I use Sennheiser HD580 through Headroom Supreme portable amp from line out of my Panasonic SL S261C portable CD player, I don't use MD or mp3 players.
For home use, I listen using Sennheiser HD600 through Antique Sound Lab MG Head DT tube amp from the line out on Terratec EWS88 MT sound card (PC).
I archive my favorite albums into 320kbps full bandwidth mp3s encoded with Lame389 (yuck I know, but still a backup incase my backup CDs go bad,

).
I also listen through the headphone jack of my Harman Kardon DVD 50 deck when my family is watching tv or listening to music on the other computer (hooked up to old Pioneer reciever and pair of Infinity SM 122).
I agree with redshifter, you're a hottie Lynn. =)
If you don't mind me asking, what ethnicity/race are you? I am South Korean.
