Can one ever be "done" in this hobby?

I got that part right away......

But as you decided to embellish the lesson so did I.......

Once I retired at the end of 2011, giving me more time to actually play the full sized system instead of listening mostly through my Grados, I got restless and upgraded my cd player and speakers a year later to an Oppo 93 and a pair of Maggies. My wife was critical of the expense (which really wasn’t much considering I bought both used and got excellent deals from two kind folks) until she heard the results. We played music non stop for 15 hours the first day everything was hooked up and my only negative was thinking about how I should have done it sooner.

Would anything short of equipment failure bring me back to the marketplace as a potential buyer? Not yet... but never is a long time...

When one is 6-ft under, then it’s time to call the hobby done. 

Not necessarily.

And your evidence that Spotify works 6-ft under or auditory functions persist post-death is where?
