Guys, below was the explanation given by the installer when the Audioquest Type 2 cable was selected for this installation. This was a almost a year ago, just when I started to learn about wires and such. Is it OK to do what they did with twisting the wires together in the end when connecting to the bananas? Are there any negatives in doing so? Please read below:
"As for Audioquest, the Type 2 is the cable that I think we should use. After speaking with my rep, this would be a great solution for your speakers. It is a solid four conductor. However, it would be used as a two conductor. The idea is that there are two positives and two negatives. We share the two positives together and the two negatives together. Essentially, we are twisting the two reds and twisting the two blacks to 'create' a 13 gauge wire. This is a theory that Audioquest has about sharing conductors as opposed to using one large gauge conductor. And, it's solid as opposed to a high strand wire, another advantage according to Audioquest."
