Hi, This issue shouldn’t occur normally, but several factors can bring it on. Lack of grounding to the digital amps in ICE Power speakers can cause a low frequency mains hum or buzz sound, but this was described as a high frequency buzz in the original post, which sounds like something different…

 

I know this is an older thread but I have the same problem but appears to be a ground hum. Steve can you describe some of those factors you mention or some advice to make sure things are grounded well? I’ve also got a mix of bl3 and BL12-3s with combination of cat 8 and converter dongles driven by a BeoSystem4.
