Question about Cardas Cross cables

Does anyone know if Cardas used the same wire when making their Cross interconnects and Cross speaker cables? I'm talking about the older blue ones.

I ask this because I noticed the cables look identical (including the labelling on the sleeves) aside from their connectors. 

Maybe I'm just being naïve?
Call Cardas, they will answer any questions you have about their legacy cables. Also be wary of counterfeit cables. 

I can't call during regular business hours, so I emailed them last night.

I'm surprised no one else has asked this in the past.

You’re in luck. Cardas is very good at answering emails.
