5T00UP is a SRPVC insulated design. SRPVC is good in that it can be run thinner to keep inductance lower as it is pretty tough. It isn’t so good for RF as the dielectric constant isn’t stable like olefin and teflon.
The Vp of cable through the audio band isn’t linear, and is a BIG isue with how cable sounds. Single LARGE zip cord designs are the WORST for this as the apparent DCR is too low to adjust the Vp linearity.
I have a paper on all this on reuest with the MATH that shows what’s happening and why. This is no secret, but it is far too costly to USE the “advantage” in most systems as people won’t pay for the advantage that they can’t really appreciate in typical audio applications. Belden knows exactly what that cable tests to, how good it is, and how much it costs to get it there. Somewhere in the specs concessions need to be made.
In better systems, the optimizations of the design, Vp differential, current coherence with frequency and the target inductance, capacitance and resistance all improve the cable’s measured performance.
The part people forget, is that RESISTANCE is a PROBLEM with Vp linearity which depends on HIGHER resistance to flatten with Vp with frequency. So, we use MORE insulated and separate wires to do that but with complicated designs to then keep L and C in check.
It takes a lot to move the needle, but it can be moved to a better overall design for sure…based on REAL stuff, not marketing terms like “cross distortion” (no such thing) and many other terms I see invented with no justrifications.
I can accept LENGTH adjusted variables that are getting darn small, but REAL. When can we not hear the superposition of a better cable? We all draw that line somewhere in the sand. But, the cable’s performance is documented and valid.
I can’t accept pure BS on what cable is doing. It is truly better or it isn’t to known measure and calculation. ALL cable is.
The foundation of R, L and C are still driving the design’s critical attributes and tertiary influences that ride on those three critical attributes are elevated at the same time as the physics has to follow.
Different copper show more differences in better designs kind of logic. This is why ICONOCLAST does not change the DESIGN, just the copper, to illustrate that point. Is the $$$ copper doing anything for you? Well, now you know in your system. When do we stop paying for the superior DESIGN, and then move paying for superior materials? We let you decide and design accordingly. You don’t have to change the entire design to change the copper.
