Yesterday's experience is today's history and tomorrow's reniewed expansion..., improving and relearning process.
Everything is changing so rapidly that experienced audio people is an extinct species.
It's a figure of speech of course, to be reminded that experience comes with every single day new adaptation and keeping up with tomorrow's new trends.

An "Expert" is one who knows and accepts their system will not be perfect. Most know the deficiencies and are either willing to put up with them, or don't care.
I have several systems in my home. I know the deficiencies of each one and am willing to put up with them..... or can't afford to fix them!!
