Actually, speaker wires are the component I have experimented with the least with my OHMs. I have just not felt the need although I would say that most everything else I have experimented with including ICs makes a very noticeable difference.
I do run my OHM 100s off a pair of Audioquest cv6 speaker wires that cost a couple hundred used for two 12+ foot lengths and this works quite well as does the commercial grade speaker wires I had run throughout my house that feed my bigger OHM Walsh 5s in a separate room.
I would tend to look at the speaker cable last personally if I were looking for changes that can produce noticeably better sound with the Walshes.
