Why not? It's a matter of priorities, and speakers are a lot more important than automobiles Not that I have that kind of speakers.Oh, yes, they can.
I look for loudspeakers that are perfect for me -- even then, one of the qualifiers is "perfect for me at a realistically affordable price".
I could spend, say, $50k for a pair of loudspeakers, but I won't.
Heck, I won't spend $50k for an automobile.
