Up for sale is an 8 feet pair of Synergistic Research Signature Ten X-Series speaker cables with spades on speaker end bananas on amp. In my system I found them to offer a full and refined sound with great bass detail and a dark background. I have used them for 15 years. No Mini Power Coupler is included with these cables, even though it does have and option for a small power supply for active shielding (the plugs shown on the last picture), I think the speaker cables sound great without it and never had a MPC. So No mini power coupler for active shielding is included, No original box, just the speaker cables. FedEx ground shipping Flat rate $30.00 for CONUS.
