I've been collecting for 7 years. That said, I collected a few LP's in high school, but it wasn't until I was part way through university when I realized the difference of sound in vinyl. I became particular about pressings and began digging day and night. Here's to 7 years of obsessive digging- My first wall of records! I'm sure when I move in a few years this will locate to a larger wall which will only need more records to make it feel 'adequate'.
I should mention that I have several hundred more, but they are doubles in the closet. Not to mention my Metallica shelf and my 45's. Oh boy.
