I bought this with the idea that it would block electrical noise from the noisy water heater we have in the house. It's not like this. It cuts out most of the noise, but my Little Dot tube amp still has a faint hum that's noticeable in the quieter parts of the songs. Since the noise is proportional to the volume at the amp, the workaround is to keep the volume high on my DAC while keeping the amp volume low. I think that's acceptable as before the noise was so terrible it was impossible to hear music when hot water was running. However, for the price I was expecting something that completely solves the problem and I wouldn't buy it if I knew it wasn't. Please look elsewhere if you have sensitive equipment.
