Ah, but the truly obsessed audio junkies take it even further. He/she considers the artists he/she reproduces in the listening room each session to be personal friends.  If anyone is interested, you would be welcome to come over sometime and meet my friends Art Pepper, Stan Getz, Lester Young, Coleman Hawkins, Ella, Sarah, June Christy, Etta Jones ... all accompanied by Cal Tjader, Barney Kessel, Ray Brown and Stan Levy.  

Hey, look ... Mel Torme' just walked into the room. HiYa, Mel ...
