I have not heard any YG speakers, but I auditioned a couple Raidho monitors. Best ribbon tweeter integration I've ever experienced (I don't know if I've ever liked another dynamic speaker with a ribbon tweeter because I always hear a discontinuity).
Detail was as advertised, super fine, but smooth. And the monitors sounded big, and punched hard for their weight.
Problem was I found myself too aware of the lack of neutrality, the frequency dip they engineer in to their speakers for the further-seat-in-the-hall, smooth and rich effect. I kept finding that tracks I know on many other speakers (more neutral) were less engaging, in particular things like drum cymbals and percussion became more recessed and lost snap and drive.
I believe the YG speakers are supposed to be more neutral, so it depends on what type of character you are looking for in a speaker.
(I also agree with the concerns voiced by soix).
