I use the Cardas Twinlink on my Panny BD35, but I'm not sure it makes much difference. However, my guess is your pioneer probably has a larger power supply than the Panny and, therefore, may benefit more from an upgraded cable. In any event, the Cardas is not very costly and comes fitted with the proper connector.
