The Sennheiser e865 is a professional-grade handheld condenser microphone designed exclusively for vocals. If standard stage dynamic mics simply don't give you the extended frequency response and sonic detail that you're looking for, you owe it to yourself to try out an e865. Condenser mics are more sensitive, naturally, but the supercardioid pattern of the e865 means you'll get great rejection of both feedback and surrounding instruments and amps, making for a crystal clear sound that sounds more like a studio mic than a live mic.
