I'd assume that it's cosmetic. I asked Mr. Lee when he was still with Harmonic Technology, probably the same stuff as the AZ's.
He is great to deal with. I was so impressed with the entry level Melody Line speaker cables, I called him to discuss upgrading to the Pro-9. He talked me out of it and had me send my Melody Lines back to him to have them cut in half and re-terminated into a bi-cable configuration. He assured me I'd get 90% of the Pro-9 with a tiny investment. Does it get more stand-up honest than that?
