Question about the Magni. I've been using it with an AKG K550 with no noise whatsoever. I believe it's rated at 50ohms. But when I switch to my Sony 7506, which I believe has higher ohms specs, there's a ton of noise at low level volume as well as popping sounds at higher volumes. The same happens when I plug in my Sennheiser HD558... Can anyone help explaining this? Is there something wrong with my Magni?
I tend to switch headphones quite a bit so not sure if its an amp problem.
While I can't offer any sort of definite explanation, my Magni was dead quiet with all of my cans.
If you're using it with a surge protector I'd try plugging it straight into the wall. Other than that I haven't heard of any issues that result in noise unless it's coming from your source.
