I was experiencing a loud line hum. I am using Focal Shape 65 monitors in a PC setup. They are connected to an SVSound Sub hi pass output which in turn gets its signal from a U-DAC8 from MiniDSP. This one is connected via USB to my PC. My previous Alesis monitors put out clean sound, but I was looking for a sound quality upgrade. Enter the Focals. The Focals however were more sensitive to noise and put out an intolerable buzz (didn't have that problem with the Alesis). I tried a number of solutions (plugging everything into the same source of electricity, upgrading cables, USB filters, ...) and nothing worked until I happened upon the Radial SB-6. The buzzing was nearly completely eliminated. I still hear a bit if I put my ear up to the tweeter, but buzzing is inaudible at normal listening distance. Now I suppose all you pros know about this, but as a hobbyist keyboard player and music lover I had never heard of Radial. Highly recommended !!!
