I own both the Morrow MA1 and the MAC Ultra silver+ and I think the Morrow is the better sounding cable. I couldn't tell any difference between the MAC and the other dozen or so brands I have in my systems, but the Morrow made an obvious favorable impression. However, it is absolutely essential that you strictly follow Morrow's recommended break-in procedure. It sounded terrible initially so I hooked up the MA1s to my 5-disc CD player and ran them 300 hours. Now they sound great! Highly recommended.
