@frogman - re your observation #2, I think it underscores that all the gear fiddling is a hobby for its own sake and may be related to better sound reproduction in a "test" setting, but is not necessarily connected to the enjoyment of music. In fact, the two pursuits (gear and music) may sometimes be at odds: for example, believing a tweak makes a system quieter, and thus correlates to improved performance. Often, I’ve found the opposite to be true- the deadening of components against electrical and mechanical interference often robs the system of musical life. But, I say that in passing as one of several experiences I’ve had over the years, and hardly an "absolute" given the infinite number of variables in various systems. (I’m not anti-tweak, but do find that one has to consider the cumulative changes that are wrought by multiple tweaks in a system- we add one to another and don’t often judge their impact standing alone).
As I have aged, I’ve become less interested in gear for gear-sake and more interested in listening for enjoyment. They are two related but not congruent pursuits. The equipment is merely the vehicle to transport you, rather than an end unto itself. (Though I totally understand the interest and obsession with gear- it is fun in its own right, but to come back to your observation #2, not necessarily connected to music).
