For fun, I asked Chat GPT:
`Does the choice of power, interconnect, or speaker cable affect the sound a a high quality audio system?`
Answer:
Yes—but with significant caveats.
1. Power Cables
-
Effect: Minimal to negligible, assuming cables meet standard electrical specifications.
-
Why: Audio gear with well-designed power supplies already reject most line noise. As long as the power cable delivers sufficient voltage and current, there’s little room for improvement.
-
When it might matter: In environments with extreme electrical noise or poor grounding, upgraded cables with better shielding may reduce hum or RF interference. But it’s rare.
2. Interconnect Cables (e.g., RCA, XLR)
-
Effect: Small but can be audible—especially with poorly shielded or excessively long cables.
-
Why: Low-level analog signals are more vulnerable to interference and signal degradation. Balanced XLR cables reduce this risk.
-
What matters:
-
Shielding quality
-
Capacitance (especially with phono-level signals)
-
Connector quality (to avoid contact issues)
-
-
Placebo vs measurable: In controlled tests, audible differences are often subtle, if present.
3. Speaker Cables
-
Effect: Potentially noticeable, especially over longer runs or with low-impedance speakers.
-
Why:
-
High resistance can cause power loss and tone dulling.
-
Capacitance and inductance matter at high frequencies (but only in extreme cases).
-
-
What matters:
-
Gauge (thicker wire = lower resistance; 12–14 AWG is ideal for most systems)
-
Length (keep as short as practical)
-
Quality of connections (tight, corrosion-free)
-
Summary:
Cable Type | Audible Impact | Conditions Where It Might Matter |
---|---|---|
Power Cable | Low | Poor power, high interference |
Interconnect | Low–Moderate | Long runs, high RF/noise environments |
Speaker Cable | Moderate | Long runs, low-impedance loads |
Final Thought:
Most audible differences attributed to cables in high-end systems are subtle and often subjective. Spending large sums on "boutique" cables yields diminishing returns—money is often better spent on room treatment, speaker positioning, or component upgrades.
