For any of us working with high-end 2-channel audio systems for any reasonable amount of time, we've managed to collect our own bag of tricks—our go-to procedures for everything from system setup to the cleaning of vinyl.
It's what sets us apart from someone just entering this vast field of what we sometimes take for granted.
I become aware of how big our bags are when I first meet someone just dipping their toe into the waters of high-end audio. When I am asked to explain the difference between separates and a receiver. Or someone's first listen to a true high-performance audio system.
Think of how many times you've been able to make a choice of new equipment, or understand what differences a fuse or cable makes.
All that makes you comfortable in interacting and enjoying your two-channel audio system—from the music you select to the volume levels you listen at—are bundled into your bag of tricks.
I trust it's full.
