Hi everybody, I hope everyone is doing good. I have been trying to live with this noise that is coming from my little dot MK 2 for the last 1 1/2 years until I realized it is not its nature, something is wrong with it.

What I Tried

* Changing tubes / Capping unused ports / New cables / New source / Ground loop stuff / Almost everything.

It is very audible in all my IEM's and not audible in GAIN 1 on HD6XX, very mildly audible in the silence 75% pass the volume port at GAIN2, Half past GAIN 3, and audible all over past 10% on GAIN4 (highest).

I initially thought this is something wrong with my IEM's being super sensitive but even though I can't hear it, it's in my HD6XX in all possible settings too.

I managed to record two audio files of the noise and I really appreciate your professional advice on what it is. If its the nature of the Little dot MK2, Then it can't be helped. But if its something wrong with it, I can always get it fixed.

So far I felt that it is coming from the Gain Stage of the amplifier.

I almost forgot to mention that the recorded audio file is at full volume GAIN STAGE 3 of the amplifier. If I go to stage 4, it will be louder.
