Does'n this invite you to re-wire the TH-900 Balanced ? Has someone tried ?
I already have.

I accidentally put TH900 on the maximum volume on DACmini can this damage them or I shouldn't worry that much ? (I simply love them)
I not only think it, there are measurements to back up my thinking. Roll your eyes elsewhere.

Cumulative spectral decay (CSD) or waterfall plots measure energy content over time across all frequencies based on a "sound burst" that excites all frequencies. They are sort of like a FR over time (technically not really as they measure energy throughout the band in successively smaller windows over time.) These plots are a good tool to "see" driver ringing or resonances (seen as ridges), which typically sounds bad (piercing, glare, shoutyness, etc.); and how fast and cleanly the driver decays (speed and extraction of low level information.)
For a perfect or near-perfect response, the decay should be immediate. We first see a wall (meaning all frequencies are excited) at the beginning. The next few fractions of a millisecond, the wall collapses into silence (meaning the driver is no longer vibrating or sound waves are no longer bouncing around inside the headphone enclosures.) The back wall at time = 0 is basically an uncompensated frequency response. Success plots over time move toward us.

For how long? The TH900 are rather sensitive headphones, so theoretically they're more prone to damage by extremely high volume...
