Purist Audio Speaker cable question

Best value is a matter of perspective. Many think that Proteus is the best value. Venustas and Corvus have Ferox and Proteus has traditional fluid. Also, Corvus and Proteus are single crystal and Venustas is not.
A lot will depend on your system and your taste.
Some people combine Ferox and fluid Purist cables.
Personally, I will take Proteus any day both for SS and tube amplification.

Corvus is a relatively new cable in Purist line. I haven't heard it or read much about it. So, who knows, maybe it is the best value for most systems? I just like their fluid cables for that incredible midrange and soundstage depth. Never tried their Contego cables which is a kind of mixture of fluid and Ferox. Some say the Canorus top of the line cable is beyond belief.
