What XLO digital cable do I have?

I also have a green and purple speaker cable that I bought at Audiogon. I guess it must be the XLO Type 5, but is it Reference?? Who knows. there's no identification of model on it anywhere, but it is stiff and I think later models were advertised as flexible, so ... between the various types (5, 5a) and the various models Reference, Reference 2, Signature, it is completely mystifying. I think someone is now listing for sale an XLO Signature 5a, does such a thing exist? And he's asking only $75, which is impossible to believe if it is really Signature line (unless it's hot I suppose....)

Hi,

With XLO, it's all in the colours. I have Reference 5A. Its white with 2 (thin) purple strands and white w/ 2 green, in a twisted pair. You have type 5. Type 6 and 6A are equally confusing.
Cheers,

Wow, you guys are really smart on the topic. I own a 7.5 feet pair of XLO cables with no model number. They are green and purple twisted - but a slow twist running down the length. Each individual wire (purple and green) has many little wires that are insulated and colored the same way. Any idea which ones I have? I need to sell them because they are too long. They came as part of an expensive bundled deal. They are about 20% nicer sounding than my previous high end cables.
