Proteus was discontinued at LEAST 10 years ago. There were no issues with it as far as I know, but it was replaced in the line, just like the Colosseus was. Upon occasion, when a significant enough change comes along, Jim at PAD will retire certain model names.

It appears that the PAD Proteus Rev B was not kept in he PAD line for very long; were there issues with this cable? How does it compare to the new Venustas line, which is actually cheaper than the original Proteus Rev B?
