Hegel hum?
Spent a week or two enjoying my new H400 and noticed a faint hum between the time I turn it on and before I play music. Also there when I pause after playing a while. Note that the hum is only apparent when I bring my ear a foot away from the amp. I’m quite pleased otherwise but am wondering if this is normal?
dave543210 Very interesting info. Thanks for sharing. |
Received my H400 today to replace my H390, watched YouTube videos saying power supply now has a DC blocker built in. I had a lot of DC hum from the H390 but my Puritan PSM156 killed most of it. However the new H400 has a low pulsing hum which I am surprised to hear given what was said in the reviews, one of which said it was now dead silent (the Canadian guy Mr Chibbs I think) It is odd as it pulses and can be heard in my dead silent room. It is plugged into the Puritan but even on a normal mains socket still the same low level hum. Have played it only for a hour or so and the improvement in sound is apparent over the H390 but quite annoyed that it still hums. Seems a couple of people in this thread have the same issue? Dave543210 is describing exactly what I am hearing so maybe they haven’t made the H400 silent after all, sigh… |
