Finding a good interconnect cable is no problem. However, at under two hundred euros, it’s much rarer. We’ve unearthed this little made-in-Germany marvel at a price that has absolutely no impact on your budget. Welcome the Viablue NF-A7 RCA.
Founded in 2001, German company Viablue specialises in top-of-the-range accessories for high-fidelity systems. Based in Malsh, close to the French border, the company offers a wide range of turned-metal mechanics and high-quality cables.
We’re going to take a closer look here at the Viablue NF-A7 RCA cable. This is an unbalanced signal transfer cable. As its name suggests, and as is the norm in this field, it has RCA plugs at both ends. The purpose of this type of cable is to carry very low amplitude signals between, for example, a source and a preamplifier or to an integrated amplifier. They are also commonly used to link a preamplifier to a power block. However, these signals are fragile and sensitive to electromagnetic noise. Shielded conductors are essential for effective protection.
To guarantee total signal protection, the Viablue NF-A7 RCA cables feature triple shielding. The first layer is based on an OFC copper-based spiral shield. This is then covered by a thin PET aluminium foil. Finally, a tinned OFC copper braid reinforces the shielding. The cable core, made up of 19 strands of OFC copper, is thus perfectly protected from surrounding electromagnetic interference, whatever the frequency.
However, while protecting the signal is essential, ensuring high-quality contacts is just as vital. To this end, the plugs fitted to these cables have a mechanical design that guarantees good contact pressure and are plated with 24-carat gold.
The sound of the Viablue NF-A7 RCA
Don’t let the price fool you, because not only is this model very well made, it also works surprisingly well. The essence of recorded music is there. The spectral balance is completely realistic, with enveloping bass and highs that are gleaming but not dry. Between these two extremes, the midrange blossoms delicately with a reassuring presence.
Rhythmic tracking is successful, giving the sound a lovely dynamic feel. Whatever the type of music being played, there’s no mechanical aspect to it, and the articulation is beautifully supple. Of course, one could wish for a little more finesse, a little more resolution, and a few details here and there, but all in all, listening to the Viablue NF-A7 RCA is hardly frustrating. And frankly, at the price it’s offered at, this cable deserves nothing but praise.
Our conclusion
There’s little point in having high-quality components if their interconnection isn’t up to scratch. This is particularly true when it comes to routing low-amplitude signals. With the Viablue NF-A7 RCA, there’s no question. However, being used to cables of a certain price, we didn’t take into account the desires of audiophiles on a tight budget. With this model, the German manufacturer is going to make a lot of people happy. The essentials are already there, for an extremely worthwhile investment.
