Which implementations use all connections of the four-pole output of the purifi module?

The output impedance of 1ET9040BA is significantly lower than the resistance of even a single high quality output binding post. To derive the greatest benefit of the ultra-low output impedance, 1ET9040BA is fitted with a four-pole output connector which permits bi-wiring. This prevents load dependent currents from e.g. the bass section of a speaker from impacting the mid/tweeter section. 1ET9040BA’s ultra-low output impedance offers a degree of isolation that can otherwise only be matched by full bi-amping. <-- datasheet

Speaker connectors for bi-wiring should also be available and the PSU should support the maximum possible output power of the module(s).
