Seeing @ghdprentice called a fool - Now I remember why I stopped posting here for many months. But since trolls need feeding, else they wither and die, I will state that not all drivers are off the shelf and cost a few hundred dollars.
While the vapor deposited beryllium coincident drivers in My TAD’s are expensive, they supposedly cost millions in R&D to develop over many years, which has to be factored into the price.
When Andrew Jones created much less expensive coincident drivers for the Elac Adante,which I use for LCR home theater, they were also bespoke, not off the shelf.
I put together a well performing $8K simple system based on a Hegel H190 when I was away from home for a year.
When I finally returned home and fired up my system that cost around 15 times as much, it was evident that one system made pleasant, enjoyable sound, and the other recreated a more than decent facsimile of live musicians playing in my home.
The other aspect of having systems that perform at this level is that small changes/upgrades (like going to Cat 8 Cable) play huge dividends, which counters the traditional thinking about the law of diminishing returns.
My reference is not other hifi rigs, but live acoustic music played in small or home venues, which I used to attend regularly, and I tuned my ears to that.
