I just bought a moon 700i Integrated amp.and only since then, I can ear a little noise (zzzzzz) when I am within 6 inch of the tweeter (both side). My speakers are Focal Alto Utopia, that I bought 1.5 year ago
I can ear the noise when there is no music playing or when the amp is at standby.
The shop who sold me the amp is telling me this is normal with this kind of equipment, the amp is so sensible and tightly built. Apparently, they also called Moon and the confirm that it is normal.
I would like to know if any of you have ever experience that kind of situation, is it really normal and what can be the cause.
