Yesterday, I decided to give up the unequal struggle and buy a Cambridge Audio AXR100. It's much, much quieter generally, the optical inputs seem like a very good idea, and there's no noticeable hum. It's like night and day, and I'm delighted - even if I have spent more than I'd hoped. Gavin

I did all this. There were no earths in the sockets anywhere, so an option might have been to set up a star type earth network.

No.

It's going to happen, I think. I'm still far from sure about the causes and what I can do about them, but there's definitely interference going on. Gavin

My Rega turntable is so old, it actually has an earth lead ;-) I needed to be convinced that the problem is not of my making before fessing up; but I will now say that it's a Yamaha RS202D. Gavin

I did nothing. I just went next door into the kitchen for lunch. I am. What would you recommend please? Thanks, Gavin

I thought we were on to something, thanks to twinkletoes. I unplugged the HDMI cable from the DVD player to the telly at the TV end, and the one-sided hum stopped. So I wrote a note here to explain and say thanks. But now the hum is back. Hey ho...

I unplugged all the inputs, took the receiver out of the hifi furniture unit and plugged it into a plain 6-way power extension with no USB PSU sockets. The left channel is still humming, though /perhaps/ a bit less. The right channel is nearly silent, as before. Presumably this is best I can...

Googling around suggests hum is a common hifi problem (which I knew) but not that it's associated with this model, particularly.

All except the Bluetooth input - but I guess that's suppressed when the Bloot isn't paired with anything.

I tried unplugging all the inputs, and the left channel still hummed. Is there anything further I could try to isolate it further somehow?

I'm not keen to mention the model, as I don't want to be unfair to the supplying businesses; the issue could conceivably be due to something external to the receiver. I will say that it's a 100W/side stereo receiver from a well known name, and that experience has shown that I need this level of...

Does anyone have any advice please? A week ago, I purchased a hifi receiver and on connecting it up, found that it suffered from an annoying hum in the left-hand channel, while the the right hand channel was much quieter. I tried every remedy for hum that I could think of and also tried...
