The 3rd one is an interconnect to use with your Dap and Amps. Only cost $20 that thing looks amazing and is silver coated copper wire. In fact all those cables I just posted are silver coated copper cost about the same as the Zus as well. I am considering trying out one or two of these I just posted. Danny got another cable so there will be some comparable cables we will find out about soon enough.
No worries. Like I said those guys aren't the only company making nice higher end cables..It is what it is unfortunately.
