What's your definition of analog smell?

I was posting on a different topic when all of the sudden I realized that the matter might be worth topic of it's own.
What do you associate with analog gear smell?  I am quoting myself below...
" The smell of an old tube reel to reel (mix of smells of oil, hot metal, hot tube glass, tape flakes and rubber belts) is the very definition of "smell of analog" to me. I need to get me a tube reel to reel just to smell. "
Can't wait to read your posts!  Happy Saturday night!  Don't know about you guys, but I will be diving a bit later into a simple (or not) pleasure of a little Jack Daniels and a lot of vocals with a single instrument.  I just replaced all cables with Acoustic Zen and music no longer "comes out" of my "Gunned" Magnepans, it "pours out" of them like highest grade extra virgin olive oil.  I don't know how else to describe it  Happy listening!
