Affordable vs. ultra expensive speakers - what's the difference?

@simonmoon

Well put. Value is highly dependent on many things.

Only working a few years in 1979, I took out my first loan to buy the state of the art… Pass designed Threshold s500 for $5000. The average car back then cost $6,000). That amp in todays dollars is ~ $19,000. 

I haven't seen any measurements on YG other than some back in 2013 on Stereophile and those were nothing to get excited about. If you want aluminum I'd take a pair Genelec 8361a for $10k with GLM and adjust to my room. For another $16k toss in the W371A and I'd be at my end game.

The only thing for sure is a lot money (the difference). The rest all depends.

It’s difficult to judge a pair of speakers based on the frequency response plot.  There are just too many parameters.
