Jetter, I have the SP-14s. I just hooked them up, not sure how to hook up the ground wire so I have to call Cap to figure that out. But just the speaker cables alone, there was a noticeable difference between the SP-14s and the Canare. The SP-14s sound thick, big, weighty, instruments have a lot of meat on the bones. The Canare sound kind of thin in comparison. I would have not thought of that of the Carare, but next to the SP-14s, that is indeed that case. This is a right out of the bag comparison, so if the SP-14s improve over time, like I said of the Prestige IC, it's just gravy.
