yup the 2000d is the better one. older model with out the plastic end caps. has 180 amp draw, .05 stable real power. 2001d if im correct there saying its digital. also its only 120 amp draw, .05 stable. both stapable even tho there both class D amps. optidrive's are not bad at all they put out, like one night stands. i have the 6000d and i would not change it for the new 7001d.
