Yes, the Sogon has 4 conductors of 24 strands each, so a single Sogon can be used a biwire cable. This means it would be 24 strands per speakerpost in biwire configuration.
If Spx is used for biwire, you would need 4 cables, each with 27 strands.
If it is as you say, that the strands are the same, and sounds the same, the more there are of them, the better the sound..
The reason i am debating this, is that it seems to be a better buy to go for the SPx than the Sogon. Reason being that you get more strands, it should sound better, AND is less expencive.
I hope this was more clear.
(my mistake to mix up the Sogon interconnect in this with 50 strands.. of course the Sogon speakerwire has 96, but the original question is the same. By the way, the SPx has only 1 conductor, not 2)
