@jwhite - The Stereophile review of the Kef LS50 Meta may be of some interest to you. In the Measurements section, the reviewer stated "The partnering amplifier needs to be comfortable driving 4 ohms."

FWIW, I have owned a pair of the original LS50 for five years and can attest to their current-hungry nature. Good luck with your Metas.
