Dear forum members,
I have already searched a great deal on this forum to try to find an explanation for the following issue, but have not yet found a clear explanation. Maybe you can help me out:
I experience a humming sound (also white noise, but that is almost not audible and seems normal to me) from one speaker only. It only appears after playing a song (or after being turned on for a while and on every input) and stays constant after that (independent of volume level). I can hear it from around 3m away.
Sometimes I also hear a 'thud' through the speakers after having turned the Nova off. This is less a problem for me, but just to check that it is in fact normal.
I have tried switching the speaker cables on the Nova and the noise problem moved to the other speaker. This tells me that the issue is not with the speakers or the speaker cables.
Sometimes when turning the unit on I immediately hear the noise and also more clearly, but then I just switch the unit off and on and the issue is gone.
Some information about my setup:
- Marantz receiver connected to Nova via RCA (for surround sound)
- Stereo speakers (B&W CM9) connected to Nova via Audioquest biwire 6m long cables.
- Whole setup connected to APC together with all entertainment equipment (TV, router, ...)
I've already taken the unit back to the dealer, and there it plays without any issues.
I hope you can help me to get rid of this annoying sound, it always draws my attention away from whatever I'm playing. I'm happy to respond should you need additional info.
