Please allow him to speak for himself.
I have done my best to write about each of the major parameters that can potentially impact the sound quality of audio interconnects, speaker cables, and digital cables... The only change that can be made is negative, that is... if they fail or fall short in any of these areas, the sound WILL deviate...
Series Resistance (R) – Determines voltage drop, current delivery capability, and interaction with source/load impedances.
Capacitance (C) – Creates a low-pass filter with the source impedance, potentially affecting high-frequency phase shift and bandwidth.
Inductance (L) – Increases impedance with frequency and can influence HF transmission characteristics and transient behavior.
Characteristic Impedance (Z₀) – Important for signal integrity, especially in high-frequency and digital transmission where impedance mismatches cause reflections.
Shielding Effectiveness / Common-Mode Rejection – Governs susceptibility to electromagnetic interference (EMI) and radio-frequency interference (RFI).
Contact Resistance & Interface Linearity – Includes connector metallurgy, surface oxidation, and mechanical contact quality, affecting signal transfer and long-term stability.
If the above are all within spec, then no such differences should arise between them.
With such properly made cables, you are hearing the full potential of the amplifier, source component, speakers, headphones etc. We cannot cheat physics or undermine decades of research that made audio equipment possible in the first place.
