Hello all,

I updated my Phantom Classic with DOS 2.11.3. I get a feeling that after the update the sound feels bit muffled (like higher frequency has been attenuated). I sense that the sound stage has changed.
Does anybody else feel that way...is it only me?
Is there any back to revert back and go to the old firmware?

My impression goes in the opposite direction. Wish a litte more discrete high treble.

I'm on Phantom Premier

Can't hear any difference with my Golds
