Solved! High pitched noise from studio monitors

[jason.rui.li7]

I've recently purchased the Kanto YU6s. I have them hooked up to a ASUS G750JW via 3.5mm audio jack.

The speakers sound great the first few minutes of listening, but after a few minutes, there would be a high pitched noise that starts getting progressively louder. Here is the sound: [video="https/www.youtube.com/watch?v=qTO9ODZSmNI&feature=youtu.be"][/video]

There is no ground loop, I tried plugging these in in different places by themselves and this still happens. I read a few threads on this topic, the most notable one was this: http/

So yeah, I don't know what the issue is, please help

You can try running them with a 3 to 2 AC ground lifter but it sounds like you need to get them exchanged. As a component in the amp warms up it starts to oscillate.

Are there any mitigations to parasitic oscillation apart from taking apart the speaker?
