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.

HIFISTAY's Soft Jelly uses the same circular pendulum motion as the TetraBase 80 Swing, but expanded to a quadruple layer instead of a triple layer for a vibration-sensitive source device. Thanks to this, 'Soft Jelly', as the product name suggests, helps to maximize the device's original performance through flexible movements like jelly.

HIFISTAY's Trinia +α shows a higher level of performance by adding +α to the existing Trinia model and improving the lower vibration layer and internal material change. The Hardpoint has been designed from the ground up to function as a state-of-the-art anti-vibration device. The term 'hard point' is derived from automotive engineering, meaning the best design for optimizing the movement of the suspension.

HIFISTAY's Dharma is a stabilizer, damper, pedestal, and resonator item that gained popularity in Korea with various functions and excellent sound quality. This Dharma is a sequel to 'Klaud Nain', inheriting various functions and performance, increasing the number of STS balls to 5200 to further reinforce the effect of the resonator, and applying the newly developed Swing Technology to the lower pedestal to improve the vibration damping ability.

HIFISTAY's Ballerino Speaker Isolation features three versions of isolation, the first being 'Single Swing' which consists of one horizontal layer of HIFISTAY's proprietary spherical pendulum swing technology. The Ballerino Single Swing is suitable for smaller and less weighted bookshelf speakers. The 45 Single Swing supports speakers up to 20kg per foot, altough it is recommended for 7.5kg per foot. The 60 Single Swing supports up to 40kg per foot, altough it is recommended for 15kg per foot. Due to the mechanical nature of the Ballerino series isolation, the recommended weight per foot is less than half of the maximum supported weight to effictively function as intended without putting excess strain on each individual component that makes up the Ballerino.

HIFISTAY's Ballerino Speaker Isolation features three versions of isolation, the second being 'Double Swing' which consists of two horizontal layers of HIFISTAY's proprietary spherical pendulum swing technology. The Ballerino Double Swing is suitable for lighter and smaller floorstanding loudspeakers. The 80 Double Swing supports speakers up to 80kg per foot, altough it is recommended for 30kg per foot. Due to the mechanical nature of the Ballerino series isolation, the recommended weight per foot is less than half of the maximum supported weight to effictively function as intended without putting excess strain on each individual component that makes up the Ballerino.

HIFISTAY's Ballerino Speaker Isolation features three versions of isolation, the third being 'Triple Swing' which consists of three horizontal layers of HIFISTAY's proprietary spherical pendulum swing technology. The Ballerino Triple Swing is suitable for most floorstanding speakers, including heavyweight speakers over 150kg. The 80 Triple Swing supports speakers up to 100kg per foot, altough it is recommended for 40kg per foot. The 88 Triple Swing supports up to 120kg per foot, altough it is recommended for 50kg per foot. The 130 Triple Swing supports speakers up to 160kg per foot, altough it is recommended for 60kg to 80kg per foot. Due to the mechanical nature of the Ballerino series isolation, the recommended weight per foot is less than half of the maximum supported weight to effictively function as intended without putting excess strain on each individual component that makes up the Ballerino.

HIFISTAY's V4 spikes are fundamentally different from your traditional steel spikes, especially those supplied with your speakers. There are 4 different variations of spikes available from HIFISTAY, starting with the simplest design, the Flip Spike, their height-adjustable Lutz Spike, the dual-motion swing Double Axel spike and all the way up to their flagship triple-motion swing, the Triple Axel spike. All of the spikes are made from duralumin and stainless steel, with a ceramic ball bearing as the contact point. The recommended load bearing per spike is 40kg for Flip & Lutz, 70kg for Double Axel and 120kg for Triple Axel.

HIFISTAY's Stella range is a collection of technology and know-how culminated in to an exceptional isolation solution for the money and size! By combining a three-layer composite pyramid structure with ceramic balls made of zirconia, the Stella Double Swing offers an excellent vibration control solution for improved sound quality. Due to the Stella being made from high-density stainless steel, as opposed to Duralumin, the sound stage appears more stable with greater purity and density in the mid range.

The iFi Audio DC Blocker+ is an essential device for ensuring the best possible audio quality. By preventing the disruption of AC power from various interferences, it allows your audio system to perform at its best. The DC Blocker+ also eliminates transformer hum, which can be a common issue with amplifiers. The bigger the amplifier, usually, the larger the toroidal transformer — often sensitive to residual DC voltage. Simply add the DC Blocker+ at the IEC to stop DC from getting in.
