At this point, I knew what I wanted and bought my QDC V14, so now I'm just watching for anything actually revolutionary that piques my interest.
QDC V14 are very nice IEMs. I don't really think you'll find anything revolutionary, but rather something different such as tuning manipulation in the phase response of multiple driver types alongside with FR curves to simulate better depth perception. Do you prefer the technical aspects of a DD driver in the bass i.e. slower decay (longer CSD) or you prefer the faster decay (shorter CSD) of the BA bass?
