The excellent ifi DC Blocker will reduce or eliminate hum coming from the transformer of power amplifiers and other hifi components.
Bye bye mechanical hum.
Many large amplifiers have a really annoying mechanical hum (emitted from the toroidal transformer itself).
You can hear it when you place your ear close or next to the chassis.
This is caused by a small amount of DC voltage in the mains which makes its way through to the mains transformer, it will become ‘saturated’ and start to hum like a trooper.
TheDC Blockeris a clever device that you place at the IEC (at the rear power inlet) and as its name implies, it stops DC from getting into the amplifier. It therefore eliminates amplifier transformer hum.
All the benefits of cutting out annoying hum with no drawbacks.
Intelligently stops any DC voltage from the mains to eliminate transformer hum
EMI shielding is retained
Equipment safety is unaffected
The bigger the amplifier, usually, the larger the toroidal which is susceptible to residual DC voltage. JUst add the DC Blocker at the IEC to stop DC from getting in.

The clever little ifi GND Defender will reduce or eliminate hum coming from ground-loop issues associated with your hifi system.
The optimum configuration for each system is one Ground/Earth for the whole system. If a system has multiple Grounds/Earths, then it often creates unwanted ground loops. These systems will then have an annoying low-frequency …
The Puritan Proprietary Dissipative Technology Mains Cable really does make a difference! Costing a fraction of some of the big brands, with none of the hype (and marketing budgets) the Puritan cable is an honest product at a very reasonable price.
The Puritan PS108 and Puritan PS108D are hand-made in Oxfordshire by skilled technicians, they are not a massed-produced Far-Eastern product. They work-wonders in terms of mains purification where budget or space is limited .
For the purist, the PS108 “Purist” model comes with no filtration, no voltage clamp protection, just the very highest integrity independent star wiring of live, neutral …
The Puritan PS106 and Puritan PS106D are hand-made in Oxfordshire by skilled technicians, they are not a massed-produced Far-Eastern product. They work-wonders in terms of mains purification where budget or space is limited .
The PSM 106 has 6 directly star connected 10 amp outlets each individually filtered against cross contamination. With a total of 19 finely tuned filter element stages, …
