Radio Gaga – the war against RF

Zapperators

A proprietary accessory which facilitates signal cleaning from ambient microwave pollution to improve the performance of your hifi. Its called a Zapperator, and plugs in-line to the end of your speaker cables as they enter the speaker.

The Technical Description

“The Zapperator is the world’s first flexibly deployable, audiograde RF
terminator/absorber”

The Theory

You may be aware or unaware of the war being waged on your hifi equipment by RF, or Radio Frequency. All metal wires – interconnects and cables in particular,  act as radio aerials, picking up broadcast signals. They are behaving in exactly the same way as your actual domestic radio and TV aerial, they can’t not do, it’s how things work. As a result, it is argued, the musical information passing through the wires is contaminated with low level radio signals. This will affect the most vulnerable  parts of music – the attack and decay of notes and an overall lack of clarity which is lifted when RF is removed.That’s the theory at least.

The main defence against RF is the manufacture of cables which are deliberately  imprevious to RF because of their design – cable consisting of multiple twisted wires properly terminated which resist picking up broadcast signals. That  is what high-end cables do and why they cost a lot. In my experience they make a very significant improvement – after they have burned in (which typically may take six weeks continuous use)

The second line of defence is to provide a  sink into which any residual RFcan be dumped – especially at the speaker end, which has its own RF-attracting internal wire. That is where the little zapperators come in.

Do they Make any difference?

In my system, yes. They have definitely helped enable better control of bass, resulting in improved balance between bottom and the  middle and top end.

Though one of the initial aims in hifi improvement for many people is to get “more bass” – its something they feel they lack – the unintended price of more bass is leaching power from the other end of the spectrum – the top end. A lot of early improvements I made gave me more bass, but killed off the top end. The more that powerful bass was controlled, giving it dryer detail and texture instead of just boom, the more the other end of the spectrum is allowed to shine.
