@wynnosu. It's been a while since this thread was active. I have an exact same problem that you mentioned in this thread. Did the noise go away after you replaced tubes. Did you do anything else? Thanks.
Audible Illusions hiss
My AI Mod 3 has noticeable hiss in both channels. It does not get louder as the gain is increased and is not present when the mute button is on. It also does not matter which source is selected.
Someone said the tubes in these can make a big difference. Does anyone have any experience in this area? Thanks.
