You're not missing anything with the ADAs when they're not tripping. I can attest to the specified peak power levels on the 1000 and 1500.
Now check out the M5s without and with a sub. You can hear HP driver artifacts without the sub for sub-bass at 107dB SPL from 13 feet away. This is a very extreme condition. It's amazing the drivers are staying in tact...LOL! You don't hear those artifacts with the M100v4. Incidentally these are dual M5s in parallel which is a 3 Ohm load in the low end and a 2 Ohm load in the mids.
These ADAs and speakers are the real deal!
no sub
