If one of your audio components suffers from an irritating transformer hum, then the DC Blocker is the perfect product for you. By intelligently blocking DC voltage greater than 1,000mV (the main cause of humming), the DC Blocker can eliminate the transformer hum in your equipment. The DC Blocker manages this while maintaining equipment safety and EMI shielding to ensure there are no negative side effects. Additionally, the DC Blocker can be used anywhere around the world!

If you can hear a consistent hum coming through your speakers, whether playing music or when idle, then you may have multiple ground/earth connections in your system causing a ground loop. This ground loop can be fiddly to fix, however, iFi have come along with an intelligent solution to help solve this issue. Enter the GND Defender! By using a specially designed AI Ground Detection, the GND Defender can automatically disconnect the ground on your device if there is a ground loop, eliminating the low hum through your speakers. But it does not stop there, the GND Defender can even reinstate the ground connection to pass current if any faults are detected in your system. This ensures a safety fallback to help protect your equipment.

If you have identified that you have a Missing/No Earth, then the Groundhog+ is for you. Its sole objective is to put the Ground/Earth back into your system and banish those unwanted, audio pests. No predicting the weather with this hog! All you need to do use a standard IEC power cable to connect the Groundhog+ to your audio system. The Groundhog+ then adds back the missing Ground/Earth connection to dissipate noise.

If you're looking to improve the quality of your sound system, the Nordost QSINE Enhancer is an ideal buy. This plug-in provides a unique solution that helps to reduce EMI noise and improve the audio/video performance of two-channel and home entertainment systems.

If you're looking to improve the quality of your sound system, the Nordost QWAVE Harmoniser is an ideal buy. This plug-in manipulates the sine wave by introducing a precise range of pulsed frequencies onto the AC line, clocked from the original 50 or 60 Hz waveform. As a result you will notice increased imagery and dimensionality to your sound and a more dimensional and vibrant picture from your AV system.
