I purchased speaker cable from Greg Straley. His website shows only one speaker cable, but he also offers different wire he recommends for Class-D. This cable is thicker, single strand per terminal versus the thinner dual strand per terminal of his standard. Both cables are wound around each other and have heat shrink sleeves at each ends, one of which shows the direction flow to the speaker. I have 2 of the Spectron III, Mk2's, but have not yet wired them as monoblock. Each of my speakers have a panel and a woofer module, so each amp runs a panel and a woofer module. I tested both Greg's standard and the optional cable and ended up going for the optional cable on both panel and woofer module. The optional cable, for me, was more forward, detailed, and presented more bass impact. I would go with his standard cable if your system was already on the bright side. I do anticipate I will go down the monoblock path with the Spectrons, but will require 2 more amp channels for my woofer modules when I do so. In anticipation of doing this, I requested Greg add one more heat shrink tube for a pair of the option cables. This extra tube has not been shrunk and is loosely on the cables. When I try the monoblock configuration, I will cut the current sleeve to allow me to unwind enough cable for the width of the amps. Depending on whether I stay with monoblock or go back to 2-channel configuration, I will shrink the extra tubing to secure the cable. Greg's cables are very reasonable in pricing, and he allows you a return period to audition. I had him initially send me both standard and option to audition both to compare. I recommend working with him.
