While it is true change can happen with the flip of a switch it is more likely to occur in small ratcheted increments.
Big events like the time years ago when one of the Genesis loudspeakers I had traveled halfway around the world to set up fell over and broke in half, are certainly instant life changing events. But they are the exception, not the rule.
In fact, most of the changes in our HiFi system (and our lives) happen in steps along the journey. It might feel life-changing when we add that new power amplifier or change those speakers, but in fact, it is just part of a long chain of events that got you here in the first place.
It is probably beneficial to most of us to remember that each step of the journey gets us closer to where we want to be: moving forward.
In the end, I believe it is forward movement that we all seek. Progress and change simply provide the steps for us to get there.
