For me, the Genos sounded tinny compared to my Tyros 5.. But I quickly adapted to it.. I use it in a studio, and don't mess with it's EQ settings too often. Of course with different speaker systems, one would be wise to try out different EQ and compression settings, because of the characteristics of your amp and speaker system.. One can easily compensate for initial reactions to its sound.
I'd feel very uncertain going into purchase something, that I wasn't excited about. You're already setting yourself up for failure.. I understand your time constraints to have to get an instrument to keep working. Just realize as with any purchase, each keyboard, piece of equipment is different on it's own merits. A Genos IS NOT a Tyros.. I think like almost everyone riding the fence when they first got one, they will be happy, (some immediate, some take a week or two).
Good luck, hope you find happiness with your Genos. I also have great faith in Yamaha (since my first DX7). They know how to make good instruments. a lot of very talented programmers, engineers, designers work on their products.. And they (like the other top manufactors) HAVE to pay attention to what people like and where musical trends are going.
Personally I have absolutely no use for EDM music. But I understand why Yamaha added them. If I was playing gigs, I might be forced to play that type of music. But there is plenty of sounds, styles, in Genos to satisfy everyone.
