Hello:
Is it normal for the buzzing that occurs when you bring your ear closer to the speaker tweeter when the speakers are in standby without playing music through the amplifier while it is on?
The sound, a kind of Ssssssssss, is felt when bringing the ear close to the tweeter, but at a normal distance it is almost imperceptible. I have tried it with an STA9 and with an AMG STA and the same thing happens in both.
I have noticed that with my AV Marantz the same does not happen.
