Joeyboynj, I too owned all of the previous top of the line Synergistic Research cables. That is, Apex interconnects, Apex speaker cables, Hologram A & D, Telsa 2 & 3 and Precision power cables.
And I had all of the Galieo mini couplers and the first generation Powercell SE.
It was all very good equipment, but the HiDiamond are better simple as that. Better and without all of the mini coupler wires! And the best thing is, at a lower price!
