How do you listen to your music?

In response to a number of articles by a certain someone regarding the quality of the listening experience - I was wondering where, how and with what sort of set up do people listen to their music. I used to make the distinction that audiophiles listened to their equipment and the music was chosen to accentuate the qualities of the equipment (hence the popularity of immacculately recorded smooth pop - read: Steely Dan - among audiophiles) whereas music fans listened to the music and chose their method based on convenience, ease of use etc. Now I'm starting to get more concerned with sound quality (to the point that I have a SACD/DVD-Audio capable set up and an increasing number of titles in these formats). So, where and on what do you listen (and I'm not asking for specific model numbers of equipment, just genral idea). Here's me:

At home:
Yamaha Home Theatre receiver (with Dolby Digital, DTS etc.)
6 speakers all Paradigm - 3 across the front, subwoofer, two surrounds
Pioneer "universal" DVD player (also plays DVD-Audio & SACD)
Sony 5 disc CD Changer

Commuting:
Stock Honda CD player

Walking:
Creative Muvo MP3 player with cheap ($20) Sony Earbuds
