My wife can't hear it, my parents can't hear it, my friends can't hear it. I can. It is incredibly subtle and high pitched so it depends on your hearing. One way to hear this to play something quiet like a quite classical part, with your ear close to the tweeter, and then stop it. You will hear the hiss continue for a second or two before the amplifier shuts down. However, while I know I have extremely sensitive hearing, I cannot hear this hiss when seated at a normal listening distance. So I am very surprised that you find it as annoying as you describe. Could you possibly make your video public so we can all hear what you sent Devialet?
I probably find it annoying as I have my Phantom on my desk, so when I'm working it's only about 18 inches away from my head, which makes the hissing very noticeable in quiet passages of music. It sounds like there are many others experiencing the same issue with their Phantoms, so hopefully it is something that Devialet are working on.
Ah! I think that explains why it annoys you particularly! Devialet are a bit in trouble with this because on their own website they say 3000W, 0 saturation, 0 distortion, 0 background noise! But I do have my doubts on whether this can be fixed in software at it seems to me to be circuit design...we shall see!
