Asking price includes free shipping to Continental 48 and no PayPal fees. This is the best cable system you can have between M Scaler and a DAC with dual BNC inputs (e.g., Chord TT2 or Chord DAVE). Includes two optical cables (1.5 meters) and four BNC cables (.3 meters). I paid $787 for the OPTO DX system in 2019 and another $200 for two PowerAdd Pilot Pro2 batteries to provide power to the OPTO DX terminals. You will need two DC cables to connect the batteries to the terminals. I paid $150 for two high quality Ghent DC-GAC4 cables. Asking price includes all of these items in great condition.
