OK. Then you will never experience the purity of single-wire to speaker!

The signal experiences pure transport, with no detours or the potential to get lost between the bi-wires.
Music is more direct and focused. More true to the artist, not showing dual-nature, no time smear due to cancellation waves between the two conductors. Dynamic timbrality and spectral liquidity are enhanced by one set of grain boundaries in one set of cables... two cables have double the grain boundaries, double the impurities, and double the oxygen. Oxygen in the wires takes the air out of the music. This is true.
So I feel bad you will miss the absolute fidelity of single wire. With the money you save on the second cable, maybe you could have upgraded to cryo...
