I'm very happy with my DH Labs Silver Sonic Q-10 Signature speaker cables. Mine are set-up as an external bi-wire but they can also be wired by DH Labs as an internal bi-wire. (Since the 3.7's only have single inputs). They are silver coated copper I believe. I also use single runs of thier T-14 speaker wire on my KHorns.
The Q-10's sound great, the outer sheathing looks impressive and well made, and they are very good values for the money. Highly recommended!
