I am a firm believer at establishing a base level for speaker comparison purposes. I suggest purchasing a pair of Canare 4S11 speaker cable from Blue Jeans Cable or the vendor of your choice. This "star quad" cable is made in Japan and a 6-foot pair with the termination of your choice is only $90 plus shipping from Blue Jeans.
You won't be the only audiophile on this site using them, and not just for their low cost.
