Hi,
I found the AZ Matrix(Copper) to have exactly the same characteristics. Slight lower-midrange boost and a little boominess on the lowend....These may have not been the latest versions of the cable. Very nice people to deal with at AZ...took them back, and offered to do some custom tweaks to the cable. Never took them up on it because I found something that suited me in the meantime.
Good luck....
