Choose for the system, not the spectacle
Good cable, sensible scale.
Speaker cable is an important connection, but there are limits to what thickness alone can do. A thicker conductor has less resistance, which can help on a long cable run or with speakers that need more current. Once the cable is the right size for the run and speaker, going extremely thick does not automatically make the music sound better.
A well-made cable still matters. Look for suitable copper conductors, sound insulation and clean, secure connections. Match the cable length and gauge to the speakers and amplifier, keep left and right runs similar, and make sure the terminals fit properly.
- Choose the gauge for the cable length and speaker impedance.
- Use tidy, secure terminations and check positive and negative polarity.
- Keep the price sensible, spend more only when it solves a real need.
In short, quality construction is useful, but the thickest and most expensive cable is not automatically the best buy. Cambridge Audio explains cable length, thickness and resistance.
