I was under the impression that the SoS cable HAD a build out resistor of an arbitrary 100Ohms? Schematic perhaps?
Dunno where you got that idea from. I've certainly never mentioned that. I'm not going to publish a schematic here, but I've described the construction (and several variations on the theme) countless times on these forums, as well as in the magazine.

"Quasi"-impedance balanced then?.....We can call them "Quibs" to further confuse the non-catered for noobs!
As Dan states, there is no impedance balancing going on. That's not what this cable is about. It is purely and simply about avoiding ground loops.
An 'impedance balanced' interface is a 'balanced' interface -- the interference rejecting properties of the 'balanced' interface rely 100% on it having matched and balanced impednaces to ground on both legs. An interface can't be 'balanced' unless it has balanced impedances!
The reason some people refer to it as 'impedance balanced' is actually to highlight the fact that only one leg carries an active audio signal and that is is therefore unsymmetrical, as opposed to the more traditional forms of balanced interface which involve symmetrical (equal and opposite) audio signals on both legs.
The term 'pseudo' means "not actually but having the appearance of; pretended; false or spurious; sham".
This cable 'has the appearance' of being balanced because it uses a 'balanced' cable and a 'balanced' connector at one end.. but it is not balanced, so it is 'false, spurious and a sham' of a claim!
Hence, it seems to be an entirely, etymologically and technically accurate phrase to use!
