Signal sources (preamplifiers, power amplifiers, receivers, etc.) are of high quality and command a premium price, yet the cabling is often substandard – a common area for cost-cutting. Some may ask: "What difference can cables make?" or "I can't hear any difference in sound!" Yet using exceptionally fine cables allows you to discern sonic distinctions. The interplay between crucial parameters—capacitance, inductance, phase shift—determines a system's harmonic character. All these findings compel us to make one decision: focus on cable construction!
