Thoughts? Grain of salt the Juhl guy works for an "audiophile" cable company
My thoughts are keep an open mind and that cables CAN "COLOR" sound by being "poorly" designed or intentionally designed badly LOL
This video is interesting as it shows actual measurement and testing of lots of cables and differences -

However, according to Joakim Juhl from OePhi Cables, they don’t tell us how a cable handles time (i.e. when sounds start, stop, and line up with each other).
So what does “time-domain performance” actually mean in practice? It’s about how a cable behaves with fast changes and real music, including:
Two cables can look equal on FR/THD but handle those fast edges very differently.
“We know that frequency response and total harmonic distortion measurements are not really that different between cables,” Juhl explained in a recent interview.
“We might see small things, but I think it’s a far stretch to say that’s the reason we hear subjectively big differences.”
Comparison tests also report the same pattern.
In Alpha Audio’s test, for instance, there are minimal differences in FR/THD, but clear spreads in time-domain behavior, including stability that can shift with signal level and load. In short, the usual plots don’t flag the differences that matter in sound quality.

Standard Tests Have Been Hiding What Makes Cables Sound Different for Decades, According to Veteran Audio Engineer
A hidden variable in cable behavior could explain decades of heated debates among audiophiles.

What Standard Tests Miss
Most cable tests focus on frequency response and distortion. And, across many cables, those graphs look almost the same.However, according to Joakim Juhl from OePhi Cables, they don’t tell us how a cable handles time (i.e. when sounds start, stop, and line up with each other).
So what does “time-domain performance” actually mean in practice? It’s about how a cable behaves with fast changes and real music, including:
- How quickly signals rise and settle after a transition,
- How much energy the cable stores and then releases a moment later,
- Whether there’s ringing or smear after sharp edges,
- How consistent the propagation delay is (tiny variations add up),
- Whether timing stays stable at different signal levels,
- And how well impedance stays consistent along the path.
Two cables can look equal on FR/THD but handle those fast edges very differently.
