the vibe amps that were good looked exactly like optis, with the opti badge removed, and one that said vibe on it instead.
even back when the GOOD vibe amps were made, there were all sorts of different looking vibe amps. i don't know why lanzar amps don't have similar cosmetics consistantly through their product lines.
there's black vibe amps, gray vibe amps, huge oversized silver amps with blue lights, etc. all called vibe, and all 2006.
the original vibe1200D put out 1100 watts, and was PWM regulated, just like the optis, and that single amp is the reason 'vibe' amps are usually regarded as good, but the only ones that are gauranteed to be good are the optis, which are about 20x more expensive than any other lanzar.
