That said, I still have a set of Buchardt A500s that measure anechoically flat down to 25hz. I paid $4500 for these. I also have a set of Shure KSE1200 that I tune to Harman with PEQ using my lifetime subscription to Roon. These were $1650 as an open box.
Aspirational ASR setups using high end studio monitors can push $10k. I believe the owner of ASR has a system exceeding $30k.
None of these purchases are within the realm of normal, they just have backing by measurements of being pretty great… things that matter in the service of verifiably good sound.
It would be wonderful to snatch that term back. The objectivism in the audio space seems to be taking a bigger mindshare as the years roll on.
Assuming you're using digital sources... roughly $500 for a decent 2.0 setup, $1000 for a nice 2.1 setup, and $1500 for a nice 2.2 setup. Less if you have the ability and knowhow to shop the used market, although the used audio market for speakers and subwoofers is kind of a pain because shipping costs effectively limit you to local pickups.
At that point you're comparing pretty favorably to a lot of things. Like a single generation of gaming on a specific console. And audio systems don't really become obsolete. They'll sound good for decades. Until capacitors leak and need to be replaced, same as any electronics.
The $10K system will be a cut above (assuming you've chosen well - it's certainly possible to spend $10K and wind up with something mediocre) but the vague price range I mention above it IMHO where you start hitting diminishing returns.

I'll also be a bit heretical here and suggest that EQ is important. Either in software, or with something like: https://www.nytimes.com/wirecutter/reviews/best-computer-spe...
However... if you're happy with your current speakers, perhaps there's no reason to upgrade! A lot of the choices I've linked to above will come with an increase in size and/or complexity. And I think those Edifiers are pretty well regarded in general.
EQ is absolutely important for the vast majority of systems. But use proper PEQ that has been derived from measurements and don't just wing it by ear. Just as important in most environments is using some sort of room correction.
Go here, sort by price, and follow the preference score, then read specific reviews for more detail about their strengths/weaknesses:

Things like the Genelec 8361A: https://www.audiosciencereview.com/forum/index.php?threads/g...
Or the Dutch and Dutch 8C: https://www.audiosciencereview.com/forum/index.php?threads/d...
That said, agreed you can put together nice systems for not much. There are systems for just a few hundred dollars that perform admirably.
Although, part of me I guess stupidly would like to reclaim "audiophile" as well.
Audiophile: crackpot with a $2000 bundle of boutique digital audio player and headphone amp hooked up to some head cans worth more than my monthly income riding the subway.
