I do not know Vandys well, but I read a 1c review that indicated some breakup noticeable at higher volumes with more challenging kinds of music. OHM 100s were also referred to as well indicating a similar situation. SOme other third speaker type as well.
I was thinking that the author might have been confusing an amplifier clipping issue with the capability of the speakers. I have heard this with my 100s where they deliver whatever I throw at them with my 500 w/ch amps but my 180 w/ch amps will give up way before the OHMs do.
Can't speak for Vandys or others in this regard but I will say that I think the OHM Walsh design is exceptional in its ability to go loud without stress, compression or breakup. Part of this is due to the high crossover frequency which puts most of the burden on the wave bending Walsh driver and asks very little of the soft dome tweeter. It also provides outstanding coherency through the midrange which is a unique aspect of the OHMs I would say. Vandy 1Cs cross over much lower I believe.
