I agree with Yerguy .... Rogue Audio amps and Vandersteen speakers are a perfect match. For many years, my system sang sweet music with a Rogue Audio Cronus (non-Magnum) driving a pair of Vandy 1C's ..... Sublime ! With the increased power demands of the 2Ce Sig 2's, the Cronus Magnum, the Sphinx, or the Pharaoh should be perfect !
