Glad that you have found a synergistic cable match with your preamp. However I would caution those reading this against the expectation that similar results will necessarily occur in other systems, or even between other components in your own system.
The Goertz writeup on this cable cites as one of its main advantages "a near match of cable characteristic impedance with the impedance at the signal source." Simply put, that strikes me as nonsense, because the output impedances of different preamps and line-level source components commonly vary all the way from a few ohms to a few thousand ohms. And unfortunately the writeup does not appear to indicate what the cable's characteristic impedance is. Also, the importance of that impedance match is highly debatable.
Also, the writeup emphasizes the low inductance of the cable, and its role in reducing noise. However, low inductance often goes hand in hand with high capacitance (as is the case with their speaker cables). Capacitance can be shown analytically to usually be the more important of the two parameters for an interconnect cable, especially if the output impedance of the component driving the cable is high. Unfortunately the inductance and capacitance of these interconnects appear to be unspecified.
My comments are not intended to diminish your findings, but to emphasize that, as is usual when it comes to cables, the performance of these cables can be expected to be highly system dependent.
