There's a "rule" somewhere that states "if you want expand some part of your life, it will pushback on others." I suppose we want to chime in and reveal our version of "the greater good", "a balanced life" and where to place our priorities. Sometimes it's difficult to separate narcissistic behaviors from efforts to improve the human condition for others. What may appear to be narcissistic at present, may in fact, prove to be a positive force for humanity years/centuries later. And, when the final "scorecard" is tallied, we may determine that the casualties (human or otherwise) were worth the price of admission for what transpired.
The goal of "the world's greatest stereo" appears to be too narrow in scope to be impactful to a large number of people, The "balance sheet" doesn't produce a positive in the column of human interaction. IF this system (and room) would have been painstakingly disassembled (like a Frank Lloyd Wright designed building), reassembled in an appropriate venue, and preserved for millennium, then we might be having a different conversation. But, it appears we got to the end of the story, without a great deal of fanfare, or perseverance.
