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.

Fog Lifters significantly reduce RF coupling, whether with the floor, or due to misdirected efforts to isolate cable with stands or clamps that themselves have too much mass and are sources of RF Noise. A few inches or centimeters might not seem important, but as with light coming from a bulb, the energy falls off exponentially. A few inches or centimeters makes a big difference—which translates into a lower noise-floor and less compromise to, and distortion in, attached active circuits.

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.

HIFISTAY's Sound Wings are developed to reduce external vibrations from affecting the signals passing through your cables by rasing them up off the floor and applying their swing technology to dissipate any incoming vibrations. The Sound Wings feature 2/3 levels of vibration control, starting with a 2-layer ceramic ball swing system in the base, a single or double silicon band connecting the two isolated poles, and lastly an optional aluminium pedestal to help fix your cables in place with a sturdier platform.
