Network Acoustics Muon 2 USB or Better

I'm looking to purchase a reference USB cable for my system, and the many reviews show that the Muon 2 is stellar. My current USB is an In-akustik reference, which is crazy good for the price. I have auditioned Infigo and Wireworld Platinum Starlight 8. The WW is the winner of the bunch thus far; it is warm but detailed. The In-akustik is a close second. I also have an interest in the Tara Labs Master, but not many reviews out there. Am I missing any other brands? Your experiences would be greatly appreciated!
