- .......I started a very similar thread ( my apology ) and much to what has been discussed here, the quality of the cable is important to a degree but it is the connections that seems to play the most importance. I am new to this side of the audio world but just purchased the Accuphase digital separates and they have a coaxial as well as an ethernet connection between the DAC and transport. It seems that Accuphase likes the ethernet connection between these two pieces. So with that said and true to Cardas Audio ......they use their own copper wires but use the very good German Ethernet connector ; Telegartner. So the wire is important but what I am reading is that the connector is critical. Thoughts ....?
