Joe-
I believe you might be trying to compare apples and oranges, as they say. I would either call Esoteric or your Esoteric dealer if you have one. There is also another thread here talking about the K-03 with some feedback from several dealers that you might want to check out. Their comments pretty much echo what I was told by my contacts at Esoteric, FWIW. Good luck and let us know if you get the K-03!
