I think that what we all need every now and then is a new music-loving friend. My GF (over 3 years now) was always into music, but didn't know what a nice stereo can sound like. It's been really fun helping her understand the nuances that the system brings to light, and in this case, her helping me discover new music.
Together, we now discover new music all the time, and at least once per week, we sit and listen to music. We talk about the artists, read the covers, check out the band on "the google", and learn. It's really amazing to see how they fit together... like how often certain artists are found on other bands' albums.
It's really fun discovering the new music, and appreciating how great music can sound in the right environment, with the right equipment, with a tasty beverage... and of course the right person who can enjoy it with you!
I've also met a few audiophile friends in the area, and I'm learning to appreciate other people's systems as well. It's an interesting way to enjoy and sample the gear without necessarily buying something.
