Ok i switched the mics, but i still have the warning, but the delay is lower, 0,29 ms. The plots are very similar to the first one, i decreased the levels. First listening, the lower delay has a impact: there is something here, this far from perfect, but that the very first time i have no more the feeling that the sound with the headphones is in my head, neither around the head but almost coming from my speakers that are mute. No virtualisation (dolby headphone, ooyh and others) never gave me this feeling, I understand now the benefit of personal HRIR. Still have a lot of work to make it better but it's a good beginning.
Any other advice to correct this delay et my bad graphs ?
Edit : grrr i've got a "hummmm" with one of the vxlr+ adaptator, not very huge, but i can hear it when i increase the input level of the mic. So more tests are useless, i've got to resend the bad vxlr+
