Y No YG ?

It's a cost no object luxury product.  Lots of money is spent on things that don't make it perform better and don't even make it look any better.  It's pure vanity.  You've got something that most people can't afford and that knowledge makes you less miserable.  meh.  

"Not only the cones, but all the metal parts in the Sonja, including the trim rings around the drivers—even the biwiring binding posts—are made by YGA. The aluminum panels that form the enclosures are milled from large sheets of aluminum."

My friends who were Veloce partnered with them at shows, and provided the preamplifier and power amplifiers, both to stellar reviews.  They felt honored to have YG choose them, and thought the loudspeakers sounded exceptional.

I've personally heard them, and also felt impressed.  That said, maybe I come across as a bit of a fraud, but I would never spend that sort of money for any audio product

I've heard several YG "models" at AXPONA two years running and at a dealer's home about two years ago. In fact, this year I thought the large YG/Audionet room was very, very good. You would need a cavern to put all the gear in--which always strikes me as impractical, but you can't fault the SQ coming out of that room. Overall, I think YGs are generally too forward for me--the top end wears on me bit by bit over time. But, in the AXPONA YG/Audionet room, that system was conducting a powerful dynamic reproduction of symphonic/orchestral bliss.  

I love my YG Carmels. 

Mark, how do they compare to your JA Perspectives?
