Choice between 2 speaker cable types.


I would like to upgrade my speaker cables and I have been referred to two well known speaker cable companies. Straightwire and Cardis are the two recommended to me. Does anyone have any experience or input regarding these two companies and the two cable models suggested to help guide me in the right direction. Straightwire - Expressivo Grand vs Cardis - Cygnus series. 
I have a rather long run between my speakers (Focal Scala Utopia) and my amplifier (Mac MC302) at 26 feet so a proper quality cable has been suggested.
Thanks so much in advance for your assistance.

StraightWire became a shell of it’s former self after David Salz left to form WireWorld. Cardas for the win.
Their DBS cables are in another league.

yup...in that league they do not publish scores...ie.basic cable physical properties :)
At 26 feet I say pick your battles. In this case admit defeat and move on to ones you can actually win. $500 in a 26 foot wire won't make hardly any difference compared to $500 in a 1m interconnect.
