Ozzy, I had a Hydra 8 before I upgraded to the V-Ray with SR Precision AC powercord and I used to considerate it as one of the most important equipment in my system, I have synergistic research cables and once the powercell was release I had the oportunity to auditionate it and without doing a direct A/B comparison in my system I just ordered the Powercell 10SE, sincerly I wasn't sure but it didnt took me too long to realize that the Powercell outperform the v-ray, I have done a couple of test pluging one power conditioner to the other and the v-ray always constraint the sound and especially in the low frequencies also the powercell has a more holographic soundstage wich extends in dimensionality immensely.
