just now sitting down to figure out logistics to compare cables. Went for 8 wire immediately as it looks like jewelry and love the sound. However, going back and forth with IEM cables takes time to switch making ABing directly difficult. Will have a better idea in the next few days. As for the standard cable vs. 8 wire, the standard isn't bad, but the Prima is definitely better. I feel it adds a richness to the A18 signature and picks up some nuances in the music that I wasn't hearing before. Cable improvements are reasonably subtle taking time to appreciate. But I can already tell that going back to the standard cable will be painful. The ergonomics on the other hand..... that weave beyond looking like $1MM adds a body to the cable that keeps it from tangling yet feels/hangs natural vs. having a cord wrapped around your neck. This is the first cable that I have attached to the A18 that adds to the look and feel rather than reduce the esthetics.
