If you want to retain the harmonic richness and 3-dimensionality so strong to the BAT products, NBS Signature is a phenomenol value on the used market. It often sells for the same price as the Cardas Golden Cross and the NBS is far and away more resolving and tonally coherent. I too liked the Harmonic Tech Magic One but it was a little too mellow and indeed did not quite have the "stage presence" that my system was capable of bringing out. I have since bumped up to use NBS Statement but I have a great desire to try the Purist which seems to get high praise from everyone. For longer cable lengths, the MIT 350 REF or EVO cables are also an outstanding value and retain the ambience and bloom of the BAT products.
