Chesseroo could be right about the difference between the VP100 and VP150, but I found that the VP150 played a little lower, but ever so slightly in the frequency range, and a little louder. That's from my experience, whether biased or not. I can only report what I perceived. After listening to the VP150, I wouldn't want to go back to the VP100. To me, at least, that says something.
