Do quality cables matter?

This is one of the most hotly debated questions in the audio world - and for good reason. Cables don’t create good sound, but they can absolutely preserve it. Think of them as the arteries of your system: they won’t improve a weak signal, but they can ensure that nothing vital is lost along the way.

1. What Cables Actually Do

Every cable in your system - power, interconnect, and speaker cable - is responsible for carrying delicate signals or power without adding noise or distortion. Poorly made cables can introduce unwanted resistance, capacitance, or electromagnetic interference, all of which can subtly (or not so subtly) affect sound quality.

A good cable doesn’t change your system’s tone - it allows your components to perform at their best, maintaining timing, detail, and spatial precision.

2. Where They Make the Most Difference

• Speaker cables: A solid, well-constructed pair with proper gauge and terminations can improve control and dynamics, especially over longer runs.
• Interconnects: Shielding and conductor quality matter most here. Upgrading from thin, mass-market RCA cables to quality interconnects often yields tighter bass and a cleaner midrange.
• Power cables: On resolving systems, they can reduce background noise and improve overall blackness between notes - though the gains are typically more subtle.

3. Diminishing Returns

There is a point where cable upgrades yield smaller and smaller improvements. Spending thousands on wires for an entry-level system isn’t wise - that money is better spent on speakers, room acoustics, or amplification. Cables should be proportionate to the rest of your setup: typically, around 10–15% of your total system budget is a sensible benchmark.

4. System Synergy and Listening

Cables can fine-tune a system’s balance. A slightly warm system might benefit from a cable that’s more open and detailed; a bright system might sound smoother with a copper cable rather than silver. Trust your ears - and audition before you buy if possible.
