The cable auditioning is over. The cables are going back to The Cable Company tomorrow. The Nordost Heindals were too lean (I suppose this is what Toetapfactor means when he referred to them as "too sterile"). I liked the detail and their control of the bass, and wanted to like them overall, but they did not have much body in the midbass and midrange.
The Synergistic Research Tesla Accelerator had a good control in the bass (not quite as good as the Heimdals, but not too far off). The high end was a bit smoother, more realistic sounding. The midbass and midrange was fuller and more engaging.
The Stereolab/ Stereovox Diablo LS was similar to the Accelerator, a bit cloudy and veiled, but a not too distant second.
