It's kinda like that certain girl, you know it when you find it. :}
I want to heard solid bass, able to crank it up when needed. I want to hear crisp high end, and clear, distinct mids. The smaller and lighter the package the better.
When someone walks into the room, I want them looking around to see where the drummer and bass player are sitting, and not looking for a DJ booth, or stand, or whatever they use.
The Ketrons do this best for me. Roland G70 is close second. Bear in mind this is for ME. Everyone has the right to their own opinions and I respect that. (As long as they agree with me).
