At the prices the really high end equipment manufacturers charge, those products should not only sound great but do so for a long time w/ virtually no reliability issues!
For myself, I judge whether to buy audio equipment or actually almost anything of at least decent quality based not only on performance but long term reliability vs the cost which then for me defines it’s ultimate “value”.
I think todays modern speakers have a good chance of lasting a long time w/ better quality drivers & crossovers than in the past but I’m not so sure about today’s complicated electronics. That remains to be seen.
