Ah, i see. It was a matter of semantics. You are looking for what I call "energy" and of course dynamic range. I will personally recommend the FX700 or EX1000s. If you want to ease your way in, the FX500 and EX600s are close to each of them for a fraction of the price. The UM3X doesn't resemble the Shure flagships all that much despite having the same heritage. Westone pretty much takes a much different approach than Shure.
