Yes, I was aware of that video even before I bought my Behringer. The video concerns a different (older) model completely, but it did make me hesitate before buying.
In my listening I could not hear any distortion. If anything, I would characterize the Behringer + M80 combo as "effortless" in producing very high SPLs. Also, after setting the gain at 26 I powered it off, unplugged it, and moved some cables around before plugging it in again and doing some sit-down listening. The volume was then controlled at the source and I do not intend to adjust the gain again, ever.
