The best reference I have is Renee Alstead's Hit the Road Jack on Tidal HD. I measured the quietest bits of that tune at 82dBC. The peaks are 103dBC and it could be that my meter is not capturing the true peaks. That's a whopping 21dB of macro-dynamics.
At my listening distance with the M5s, I need 4W to reproduce that 82dBC and 1024W to reproduce the 103dBC peaks.
The ADA-1000 can do it with the M3, M50 and M100. It can't do it with the M5. My Onk can do it with all speakers but it's not as clean as the ADAs (up to the 1000's limit). The ADA-1500 can do it cleanly with all and then a bunch more!
The M3 BTW struggles with that level above but the M5, M50 and M100 sound great.
