I'd like to hear them too. hard for me to imagine that speakers could be worth that but money is a relative measure, and if someone has the cash and chooses to spend it this way, good for them. It's not a moral issue. Problem with that point of view is that a $10,000 set of speakers is far beyond the means of many as well. Most people would never understand why anyone would "need" to spend ten grand on speakers
it's all relative and a matter of choice for those who have the means. Nothing inherently good or bad about it
