Sorry for the late response. Moved from a Hydra6 to a VRay some 6 months back. There is a difference but not as dramatic as the ads would have you believe. The V Ray is plugged into a Shunyata supplied wall wart with a Anaconda Helix cable. The system is really beginning to sound good( sorry don't have the full audiophile vocabulary!). The V Ray has 8 inputs so why not plug the entire system. Am also using a CJ power amp with the V Ray sitting on a dedicated shelf in a acrylic/ stainless steel audio rack.
Cheers
