There is no way to define sound as a “percent”. If we could, that would mean we can determine to no shadow of doubt what 100% was, and we can’t.
To some any change to or away from their ideal preference, and it is a preference, is worth solving. A perfect cable won’t be perfect to every ear even if the user knows it is perfect (tone controls anyone!).
That said, the 4x4 and 1x4 30 AWG designs tend to open up the upper frequency range as reported by most users, It is more architectural and less impressionistic art if you will.
Both cables are more transparent than typical designs as they use an air gap dielectric so either, compared to solid dielectric designs, will sound more “open”.
The BAV is an incredible design based on the design target of sound and audible performance. I love how this cable turned out. It is a wonderful option with way more sound than expected. If you were to put a percent on it I’d stick it in the less than 10% range, it is that good.
Measured electrical are slight, BAV has a 85% RF Vp verses 87% RF Vp on the Teflon ICONOCLAST design. This changes the capacitance a touch, and just a touch. Inductance is the same (no change in the loop area). Capacitance is the dielectric.
Know too, that the conductors are Both using the FEP spacer thread around the conductor so the plastic closest to the wire is FEP. The BAV does have the DOW Engage dielectric support dielectric structure to gain flex and durability. The material outside the braid shield makes no audible changes.
There is a tech paper on the BAV XLR that pretty much lays it all out how it works and why. Numbers and all that we can measure. But we have no percent of 100% until we know when we ever get to 100%. That’s impossible through a cable.
Best,
