FIIO FT1 &FT1 Pro Stereo Cable

This is an audiophile-grade, ultra-low capacitance stereo cable for the FIIO FT1 & FT1 Pro. It provides a stereo connection from the headphones to an amp or dac.

What material is the wire made of and why?

We make our wire from OFC Litz copper. Each core consists of of 84 individually insulated strands of 0.071mm diameter copper. They are held together with natural silk fibres and covered with an oversized nylon outer cover to give a large air gap between cores.

Why OFC copper rather than OCC or Silver?
For the same cross-sectional area, silver is about 7% more conductive than copper. However, if you double the cross-sectional area of the cable, you can roughly halve the impedance. It is therefore much cheaper to use more copper to get the same improvements. By using our thicker copper wire, we get better impedance figures than a thinner silver cable. OCC has the advantage of being more flexible, but as our strands are so thin our wire is very flexible already.

The advantage of Litz vs. stranded copper in terms of skin effect

With a standard stranded copper wire, as charge can move from one strand to another, they act as one thick solid conductor.
>Skin effect pushes higher frequencies out to the edges of the wire, meaning they are traveling through less of the area of the cable. The skin depth reduces as the frequency increases, so on thin cables, it’s not a problem for audio frequencies.
In our Litz wire, each strand is individually insulated from each other.  They act like 84 individual thin wires, rather than one large one. This ensures that despite the increased thickness of our wire, there is no skin effect until the frequency gets over 700khz so even the highest res audio will not get rolled off at the top.

What is the capacitance and impedance of your cable? How does it affect things?

Our cables have some of the lowest capacitance of any that we have tested. This was one of the main goals when designing it, as capacitance is most likely to give an audible effect. Typically, one of our cables will have around 20pF – 40 pF for a 2m cable, depending on the connectors used. As a comparison, a standard HD600 cable has a capacitance of 600pF.
The impedance of a capacitor changes with frequency, which is why we keep it as low as possible.
Our wire has a DC resistance of 0.05 ohms per meter, which is very low. We also keep the capacitance and skin effect incredibly low, so it gives a pretty much perfectly flat impedance across all audio frequencies, from 1hz right up to 100+KHz.

How does your cable sound?

We designed our cables to keep the signal as pure as possible with a perfectly flat response. We believe you should not use a cable as “tone control”, the sound is as good as it is going to get as it leaves the amp.
The cable’s job is to get the signal to the headphones without adding or removing anything from the sound.

What are the ergonomics like?

Ergonomics are almost as important as electrical performance. You could have a great-sounding cable, but if it is stiff or heavy, it can be distracting and spoil your listening experience.
Despite our cables being quite thick, they are mostly air inside to give an air dielectric. Because of this, they are very light and very flexible.
>As the cable has a bit of spring to it, it can also reduce the pressure on your equipment if you accidentally yank the cable.

What sort of warranty do you offer and what If I change my setup in the future?

There is a 2-year warranty on all of our cables, so if you get any problems please message us! We can repair or replace it for you for free at any time in the first 2 years.

We are keen for our cables to stay in use for as long as possible to prevent waste and save the environment. If your cable breaks outside the warranty period, we offer cost-price repairs.
>When you buy a different amplifier or set of headphones in the future, you can send the cable back to us to alter or adapt them for a reasonable price.
