Marakanetz 2 ohm dip in Vandy's 2 series? I don't think so. I believe their minimum impedance is 4 ohms but they are essentially a quite easy load to drive. This is not to say that they will not benefit by more power but I'm not sure that it is necessary, at least in my experience with them, lived with 2C's for 10 years. Maybe the newer of the 2 series are less efficient?
