Ah yes the WaPo comments section, I'm sure they're filled with the enlightened musings of some millennials living in their parent's basement breaking down a man that worked nearly his entire life while they suck on someone else's teet.
Unless you've heard the system none of us have any idea how it sounds.
That you think millennials are reading newspapers (physical or online), much less commenting on articles in them, is most amusing. Trust me, it's boomers like us all the way down.
As far as the home concert hall builder guy (RIP), I'm not jealous, I'm as fascinated as I would be with any display of obsessive behavior and terrible taste in decor. (Similarly I'm not in the least jealous of DJT's heavily gilded abodes, which he seems to think is an indicator of classy)
For all his fussing, I certainly don't think (objective) sound quality mattered that much to him, given his devotion to used LPs.
