We have found the Cardas Twinlink to be the PC of choice with many DAC's, source and preamps. The Quadlink is our least popular model (not saying it is a bad cord, but un-shielded - the shielded Twinlink will be a bit quieter). Do not let the $130.00 price scare you off, it is remarkable at it's price if used in it's correct position.
