Interesting, electronica can be pretty simple relative to acoustic instruments and vocals. So in many ways it's just not that demanding... until you ask for concert-level SPLs then it has different requirements vs classical anyways.
My main criticism of YG that I've mentioned many times is you have to spend a fortune on Sonyas to get enough driver surface area. I've heard some excellent YG systems, including at YG's factory with D'Ag amps so I know they can be really good. But I don't think the Haileys have the same potential as the larger and more expensive Sonyas, and I'm not sure the Haileys are enough to do a great job on complex music.
Whether the compromises and design approach YG takes is right for you is another issue. I just don't think the YG approach scales down that well, I'd rather have a less technically perfect speaker with larger drivers!
