I don't have a strategy. I travel through my collection and listen to what leaps out at me, and I work on the new arrivals stack. I'm retired, I love the sound of my system, I no longer drink or smoke to dull my senses and I get three to four or more hours in a day when there isn't a hell week like the last two have been for the two of us.
I know I have a huge holdings and I should be more worried about that. But I don't wonder "do I need" this or that or all of this or that. It's not about need, except the need to explore and learn about the music.
