10 years from now is when you can look back to say when stuff actually settled down and were set......for 3-4 years in a row. where changing is no longer a thought.
It is an interesting phenomena -- how do you know when you're satisfied. How do you know when you're done? Ron said
I'll know it when I hear it.
Presumably one 'hears it' when making a change or when making a substantial improvement. Presumably Ron knew or at least thought he did when he bought those fancy Gryphon speakers. Now he's salvaging that purchase by using their bass towers. Not trying to pick on him -- he's just a near at hand example of the phenomenon..
How confident are we with our confidence that 'this is it'. Maybe we can only assess that as you intimate, by waiting several years.
Can we know it when we hear it if we don't truly know what we want? Saying "I want better sound" is simply not enough, imo. I'm thinking that knowing what you want needs to start with music, real music, not a list of audiophile adjectives.
