Refined profile sounds different when stored

  • Has anybody else noticed this? I do the profile and it's never spot on so I refine and I get the sound so it's very close to the reference amp (although I've never managed 100%). I then mute the reference amp so all I can hear is the new profile in my cans. yes, sounding good. I then store and instantly the sound changes. Volume goes down, sound thins out and gets a bit harsh and gritty. I have tried system reset but this still happens.
