I sold everything that I had except for my headphones and amp and live in a cardboard box and plug my amp into an electric pole wire way up high with a long cord. I eat out of trash cans so any money I have can be used to upgrade my stuff. LOL
Amps and sources are things that are usually one time larger expenditures. I make music purchases on a more regular basis. It varies but at a minimum I will buy one or two Cd's in a month, sometimes more.
