Review on 🔇 MA Audio Ground Loop Noise Isolator: Enhance Car Audio/Home Stereo System Quality (Black) by Jon Conner

My mixer was picking up horrible noises from my graphics card on a PC. I tested them and they completely eliminated that noise. I've bought enough to use on every line of this blender and it's a life saver! I have 6 connected. My office audio system wouldn't work without using them for noise cancellation. I didn't notice any significant change in audio level or quality other than the filtered out digital noise.
