How does this make sense, any sense? Any sense at all??

shtinkydog, audio gear in the same class (for Stereophile's ratings purposes) does not imply that these products sound the same or work the same way with your other gear, music, room or ears

In a sense the ratings provide guidance as to how well the manufacturer has achieved their stated goal and objectives for the specific product. I don't think anyone expects that a $1K speaker to compare to a $10K or $50K product. If they do it's more about your emotional connection to the sound of a given speaker than the price tag.

I don't know if I can explain it any better than that.

KEF ls50 + beefy amp to drive them + powered sub can match most anything you would ever put in that same  room. 

But the sub will have to carry more of the bottom end as room size increases. 

So room size is the main determining factor for how big and likely expensive a speaker need be to perform at the highest level full range. 

If Full range not of concern then things are also much easier. 

The stereophile class ratings are only useful to a certain extent. It’s always reasonable to question what you are really getting with products that cost way more than others.

If they put a price tag of $50k on the LS50, it would be compared to other speakers in that price range. It would not be compared to $1k speakers. If they put a price tag of $500 on a magico, it would get some good reviews some bad reviews but nobody would dare compare it to a $50k speaker. Its all perception. 

Do you live in a dilapidated trailer and tell your friends that its the same as a $5,000,000 custom home?

Do you not understand the difference between a 1984 Le Baron and a 2020 Porsche?  Or are they the same because the have tires and an engine?

Is Natural Ice as good as Chimay?

Are you able to tell the difference in quality in anything or is it just Speakers that are all the same?

Does the $50k speaker have a flatter frequency response than a $100 speaker? What does the former do that the latter does not? Why dont you stop beating about the bush and show us the measurements as evidence?
